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...

We have many alternatives to sugar, but where are all the salt substitutes?

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...

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...

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...

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...

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...

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...

Ions are all around you and in many of the products and substances you encounter on a daily basis. Being able to determine the identity and difference between cations and anions is important for success in chemistry and physical science....

The Schottky defect and its consequences

Ionic crystals of type A B exhibit a Schottky defect, where an equal number of anions and cations are absent from lattice sites to maintain electrical neutrality. This defect is present...

Fajan's rules explain how factors like ion size, charge, and polarizability determine whether a bond will be predominantly ionic or covalent

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

Ionic bonds form due to the electrostatic attraction between positively charged cations and negatively charged anions, often resulting in crystalline solids

An atom or molecule that has gained or lost one or more electrons, and so has an electrical charge.
