Ionic Bonding
In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the...

Ionic Solids
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 ionic...

3 Chemistry Experiments That Changed the World
Chemistry is the study of matter - stuff, and how it interacts with other stuff. Even though chemistry doesn't make a lot of news these days, chemists are making discoveries that change lives all the time. If Hank had to narrow down all...

Covalent Bonding
In this video Paul Andersen explains how covalent bonds form between atoms that are sharing electrons. Atoms that have the same electronegativity create nonpolar covalent bonds. The bond energy and bond length can be determined by...

The EASY way to name Ionic Compounds!
In this video we are going to look how to name binary ionic compounds. These compounds deal with the ionic bonding of 2 different elements. Remember that an ionic compound is formed between a metal and a nonmetal or a cation and an...

Anion Vacancies and F Centres in Metal Excess Defects
The formation of F-centers in a crystal is caused by the presence of anion vacancies, which are caused by the presence of metal excess defects. Alkali metal halides, such as sodium chloride and potassium chloride, are examples of...
