Glass is made of sand, which is a kind of rock. But glass is transparent, and rocks aren’t transparent. What’s up with that? Why is glass clear? And why can I sit on a chair? And why can we touch anything? Today we zoom down to the weird...

What does an atom look like? Throughout history scientists and philosophers have attempted to answer this question. As a result, they've come up with some useful models for understanding the building blocks of our universe.

In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the...

When Ernest Rutherford realized that atoms have a heavy nucleus, he hypothesized that the way the moon orbits earth is the same as the way an electron orbits the nucleus of atoms. We now know an atom would...

In this video, students will learn about atomic theory, atomic structure and how the atom is put together. This will include learning about the different subatomic particles, protons, neutrons and electrons, that make up the atom! This...

Valence Bond (VB) theory explains how chemical bonds form through the overlap of atomic orbitals, where electron pairs are shared between atoms. The key concepts include: Atomic Orbital Overlap: Bonds form when atomic orbitals from...

Anions, formed by electron gain, contribute to ionic bond formation. Larger anions with higher charges enhance the bond's electrostatic attraction

Valence electrons are the electrons in the outermost energy level of an atom. They are important because they are involved in the chemical bonding of our elements which helps determine the reactivity of elements. In order to be stable,...

If you have taken a chemistry class, chances are you were taught at least 1 of these 4 things wrong: atoms are solid spheres, all solutions are liquids, chemical equation, magnetic metals. Check out this video to see if you were taught...

Chemistry can be challenging and as with most classes in school, there are some mistakes that pretty much all students make. In this video, we cover these common mistakes to help you avoid them!<br/>

It gives idea about the nomenclature, structure, properties, preparation methods, substitution reaction, meta-para-ortho directing functional groups.

Upon viewing the Exploring the Building Blocks of Matter video series, students will be able to do the following: Understand that the quest to better understand the building blocks of matter has transpired over the past several thousand...

Halohydrin Formation: Theory, Mechanism, Examples

This program makes the Modern Periodic Table come alive to students. Numerous real-life examples of elements are exemplified in the table. Animations and graphics illustrate concepts not easily achieved through other instructional...

Alkene Halogenation: Theory, Mechanism, Examples

This video explains the characteristics of electrons and their role in atoms. The concept of the electron cloud and energy levels is introduced, emphasizing their significance in determining an atom's interactions with other atoms. Atoms...
