Ionic bond
Ionic Bond
An Ionic bond (pronounced: /aɪˈɒnɪk bɒnd/) is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions. These kinds of bonds occur when a metal loses electrons, becoming a positively charged cation, and a nonmetal accepts those electrons, becoming a negatively charged anion.
Etymology
The term "Ionic bond" is derived from the term "Ion", which in turn comes from the Greek word "ἰόν", meaning "going". This is a reference to the movement of particles in a solution after being ionized.
