A unit is a frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units. Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists. So listen up and learn something or Hank might have to kill you! (NOT REALLY!)

The elements had been listed and carefully arranged before Dmitri Mendeleev. They had even been organized by similar properties before. So why is Mendeelev's periodic table the one that has endured? Lou Serico explains via eka-aluminum, an element whose existence Mendeelev predicted years before it was discovered.

About Atomic School:
Atomic School supports the teaching of Atomic Theory to primary school & science students .
We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program.

Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class!

The program has been trialed in Australian schools as well as high schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival.
It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences.

Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth.



About Ian Stuart (Email: ian.douglas.stuart@gmail.com):
The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world.

Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths.

Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

Video transcript:
From a distance, a beach looks like one big smooth thing. But if we look at it through a telescope, we can magnify it and make it look bigger. Now we can see that the beach is not smooth at all, and it's not a single thing. It's made up of a lot of little sand grains. The beach is nothing but all the little sand grains put together. 12. A beach can be made of a thousand TRILLION sand grains.
It's an example of a big thing being made of lots of little things. We could say that the sand grains are the basic building blocks of the beach. How about a forest made of lots of trees? Here's a forest up close, and here's a forest on a distant mountain. Is this Lego parrot just one thing?
We can say that bricks are the basic building blocks of the hut, or that sand grains are the basic building blocks of the beach. But are bricks or sand grains themselves made of anything smaller?
To answer this question we can magnify a sand grain to see what it's made of. Scientists magnify really small things using a microscope, which will make the sand grain look bigger. The most powerful kind is called an electron microscope which can make things look millions of times bigger, so let's use that. Our scientist puts some sand under the microscope and now she looks through the top to see the magnified sand. Here's what she sees when she zooms in. This is what she sees, and now she is zooming in more. Magnifying the sand grain a million times would let her see the sand's building blocks.
Wow, look at those. These marble-shaped particles are the building blocks of the sand. They're called atoms. The word atom means uncuttable, and if you imagine we had a very sharp knife, we could cut the sand into smaller and smaller pieces, but we couldn't make it smaller than an atom because this is the sand's smallest piece. A tiny sand grain is made of 10 million, TRILLION atoms

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

Whacky colour changes, magic disappearing water, blowing up dustbins, clouds of steam, thunder air explosions. Are you ready to fasten your seatbelts and enjoy the ‘explosive’ journey?

In his talk, Andrew aims to promote chemistry as the science of remarkable changes, which are often overlooked yet so important in our everyday life. And he does it brilliantly by performing an incredible series of 25 experiments in 15 minutes, totally amazing the audience (who rewards him with a long and deserved standing ovation)!

Andrew Z. Szydło is an internationally acclaimed chemistry teacher. But he’s definitely not the typical chemistry teacher you would expect…

He holds a PhD in the History and Philosophy of Science from UCL, and is an expert on the history of alchemy (his 1994 book ‘Water Which Does Not Wet Hands’ is considered to be the standard reference work on the Polish alchemist Michael Sendivogius.)

But his polymath spirit extends further: he’s a violin, bugle and accordion player, as well as a professional photographer. Throughout the years Andrew has wowed audiences all around the world with his pyrotechnical approach to teaching and demonstrating chemical sciences on stage and has appeared many times on TV. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Introduction video on the periodic table being explained to chemistry school & science students . The video explains how there are 92 naturally occurring elements, one for each kind of atom, and how they are arranged into a table according to their relative weights.

The expanded table is shown, and how this is abbreviated into the common Periodic Table. The division between metals, semi-metals and non-metals is discussed, with notable examples.
It also shows how the elements are arranged in rows and groups, the latter containing elements with similar properties, like members of a family.

Video transcript:
In the first video we saw that all the things in the world are made of incredibly tiny particles called atoms. And also that there are 92 different kinds of them. Most things have more than one type of atom in them, but when we do find something containing just one kind of atom, we call it an element. A nugget of gold is an element because it's made of only gold atoms.
The atoms are too small to see with our eyes, even using a good microscope, but if we could zoom in with a magnification of a billion times we could see the individual gold atoms. Each kind of atom had a shorthand way of writing it, called its symbol, using either one or two letters. The symbol for gold is Au, taken from the ancient Latin word it, aurum. The symbol Au could refer to either a single gold atom, or the element gold consisting of many gold atoms.
Scientists have made a list of all the types of atoms, starting with the lightest, hydrogen, followed by the next lightest, helium. Just heavier than these are lithium and beryllium. We could give each element a number showing its place in this list. Hydrogen's number would be 1 as it is the first in the list, helium's would be 2, and so on. Here are the first 20 elements in the list, starting with the lightest, hydrogen, and going all the way to the heaviest, uranium. Since there are 92 elements in the list, uranium's number must be 92

In this lesson, you will learn about the periodic table and how it is used in chemistry. We will focus on how the periodic table is organized by atomic number, and discuss how properties of elements are periodic in nature throughout the table due to the electrons in the outer shells of the atoms. We will also discuss atomic mass and valence electrons, including predicting when an atom will gain or lose an electron in a chemical reaction..

To explain how atoms behave, we need to look inside them.
About a hundred years ago scientists discovered that atoms aren’t like tiny solid marbles as they thought, but made of three much, much smaller particles - positively charged protons and electrically neutral neutrons in their centre, called the nucleus, and negatively charged electrons orbiting on the outside in shells. See our video about how scientists discovered protons, electrons and neutrons at the link in the descrIption:
https://www.youtube.com/watch?v=kBgIMRV895w

THE NUCLEUS
The nucleus is much smaller than shown here in the diagram. If an atom were the size of a football stadium, then its nucleus would be the size of a pea. This means the atom is mostly empty space. And so are YOU.
Even though the nucleus is tiny, it makes up over 99.9% of the atom’s mass. That’s because protons and neutrons are 2 thousand times heavier than electrons. So they don’t matter much.
In 1913, Henry Moseley discovered that an element’s Atomic Number was always the same as the number of protons in its nucleus. What a coincidence! This is now the modern definition of Atomic Number.
This atom has 5 protons so its Atomic Number is 5. This is the number above the element’s symbol on the PT. Which element is it? …. Boron.
In an electrically neutral atom, the number of positive Protons must equal the number of negative electrons so that their charges cancel. So a boron also has 5 electrons. The job of neutrons is to overcome the proton-proton repulsions, and to keep the nucleus together. Most boron atoms use 6 neutrons to stabilize their nuclei, but some can get away with 5. The number of neutrons can vary between atoms of the same kind, so scientists give these a special name- isotopes. So boron has two! isotopes.
Protons and neutrons both have a mass of about 1 atomic mass unit, or amu, or just u, or even the Dalton. They all mean the same thing, which is a bit annoying. Call me old fashioned, but I prefer amu. Scientists use this tiny mass unit for atoms as grams or pounds are too big. Electrons weigh hardly anything. So the atom’s mass is just the sum of its protons and neutrons. Both boron's have 5 protons, so its 6-neutron isotope would weigh 11, and its 5-neutron isotope 10 amu. It’s Atomic Weight shown on the PT is 10.8 and is the average of its two isotopes. It’s is closer to 11 because it’s the more abundant one.
Neutrons have a big effect on Atomic Weight, but don’t matter much in making chemical bonds, which we’re interested in here. So we’ll just look at protons and electrons from now on. Bye, bye neutrons. And Atomic Weights.
ELECTRON SHELLS
The first electron shell can accommodate 2 electrons before it’s full, while the 2nd shell can accommodate up to 8. This is why boron has only 2 electrons in its 1st shell, and the remaining 3 electrons in the 2nd shell.
Electrons are like guests in a hotel. Here’s a normal hotel. And here’s the Quantum Hotel that better shows how electrons fit around an atom. The 1st floor can take 2 guests before it’s full, the 2nd floor also 8, the 3rd floor 8, and the 4th and 5th 18 each. When a floor is full a new arrival is sent to the next floor up. This guest on the 4th floor has more energy than the guests below, which she would find out if she jumped. When she lands, the energy she had turns into sound energy. Electrons in higher levels also have more energy, and when they jump down, light energy is emitted instead. This is called a quantum jump.
