Quiz & Worksheet - Who is Judge Danforth in The Crucible? Ionic compounds are a common, yet special type of chemical compound. The opposite negative and positive charges of the ions hold together in ionic bonds, forming ionic compounds, which are just what they sound like: compounds made of ions. In this video lesson, you will learn about their formation and structure and see examples of compounds formed by ions. Ionic Compound Definition: An ionic compound is a compound formed by ions bonding together through electrostatic forces. Atoms that gain electrons and therefore have a net negative charge are known as anions. The IONIC BOND results as a balance between the force of attraction between opposite plus and minus charges of the ions and the force of repulsion between similar negative charges in the electron clouds.
