Introductory video to the hydrogen line spectrum, which in part led to the initial development of quantum mechanics.<br/>

Everyone has trouble with electron configurations and quantum numbers. Well today we are going to settle the score with a little practice!

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

With the Bohr model we start to get a better sense of the nature of matter, particularly the way light interacts with atomic matter such that we can see it. But how do we do calculations regarding these interactions? Let's practice now!

There are a number of substances that are vital to all living organisms. In this lecture, I talk about substances like carbohydrates, lipids, proteins and nucleic acids, going into some detail about their structures and importance.

In this section, I talk about elements, atoms and how they interact. I deal with two types of bonds: Covalent Bonds and Ionic Bonds. I also talk about pH, chemical reactions and metabolism.

What are the issues with the Bohr model of the atom (Neils Bohr)? Some issues with this mode helped early physicists invent and develop the discipline of quantum mechanics.<br/>

Learn about Niels Bohr's refinement of the Rutherford model of the atom.

Learn about the energy levels and electronic configurations of atoms of different elements in this video from the Properties of Matter chapter of the Virtual School GCSE Chemistry.

Learn the basics about Energy Levels and Electron Configuration. Where do you find energy levels? How do you recognize electron configuration? Find out more in this video!

In this part 2, learn the basics about the atom, particularly about isotopes, whilst learning about properties of matter. Learn the basics about the atom, whilst learning about properties of matter. Atoms are the small bits that make up...

Why don't protons and electrons just slam into each other and explode? Why do different elements emit light of different colors? Niels Bohr knew why. And now you will too!

The relationship between energy levels and strength of chemical bonds are discussed and demonstrated in this video. Students will learn that a chemical bond forms when electrons have lower energy and that less stable atoms tend to form...

This video explains all about Ionic and Covalent bonding :) enjoy!

Upon viewing the Forming Bonds video series, students will be able to do the following: Understand that matter is made up of tiny particles called atoms. Explain that atoms consist of many different types of subatomic particles including...

This video explains how electrons are arranged in atoms and how their arrangement affects the bonding between atoms. The video also highlights the importance of valence electrons, which are the electrons in the outermost energy level, in...
