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.

Lesson by Lou Serico, animation by TED-Ed.

Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. Understanding basic chemistry concepts is important for almost every profession. Chemistry is part of everything in our lives.

In this video Chemistry 101 - Atomic Structure, we study atomic structures which refers to the structure of an atom that comprises of Nucleus, Protons, and Neutrons.

Nucleus - is the positively charged center of the atom consisting of protons and neutrons.
Protons - Positively charged subatomic particle forming part of the nucleus of an atom
Neutrons - A subatomic particle forming part of the nucleus of an atom.

Our collection of videos in Chemistry covers most of the syllabus for exams such as WAEC, NECO, JAMB, and GCE.

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 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.

This video series, Basic Chemistry for Biology Students, teaches the basic chemistry that you’ll need to know in your biology course, whether that’s introductory high school level, AP Biology, or even a first year college biology course.
The series covers
1. The structure of atoms (a nucleus with protons and neutrons; electrons orbiting outside in orbitals)
2. What biology students need to know about the Periodic Table.
3. The “Octet Rule” for understanding how electrons are organized into orbitals.
4. Ionic bonding (how atoms trade electrons to become charged ions, and the ionic bonds that result)
5. Covalent bonding (how atoms share electrons to form molecules)
Key chemistry terms (element, compounds, molecules, etc).
6. Understanding chemical formulas (molecular formulas and structural formulas).
Each video is tightly linked to tutorials at http://www.sciencemusicvideos.....com/basic-chemistry-

Learning Objective: Use balanced chemical equations to calculate the amounts of products or reagents needed using the stoichiometry of the reaction.

Topics: stoichiometry, dimensional analysis

Be sure to use this very helpful trick to help find the hybridization of an atom in a compound.
