In this video Paul Andersen explains the difference between chemical and physical processes. Chemical processes occur when bonds are broken and reformed. Physical processes occur when intermolecular forces are broken and reformed. A...

In this video Paul Andersen explains how ionic solids form a lattice between cations and anions. According the Coulomb's Law the lattice energy increases as the ions carry a larger charge and are smaller. Some of the properties of...

Discover the truth about lattice energy and why size really matters in ionic bonds. In this video, you'll learn what lattice energy is, why it's crucial in chemistry, and the factors that influence its strength. Understand how the size...

While While the Bohr model of the atom is not the most accurate model we have today, it can help up show a lot of valuable information about the atom. Bohr models can show the protons and neutrons in the nucleus along with the number of...

Electron Configurations are essential to chemistry and they help us better understand and explain the position/location of electrons. Writing electron configurations can be daunting at first but once you see the pattern, you will be able...

This program covers the very important topic of ions and ionic charge. We begin by discussing the concept of an ion and how it relates to a neutral atom. We then discuss how to calculate the ionic charge on an atom with practical...
