# What are some examples of ionic compounds?

May 25, 2018

Sodium chloride $N a C l$ and magnisium dichloride $M g C {l}_{2}$

#### Explanation:

Ionic compounds can be identified by the difference in electronegativity of each atom. When the difference in electronegativity is $\ge 2$ it would be identified as an ionic bond.
E.g. for sodium chloride which consists of sodium ions and chloride ions. Here the electronegativity of sodium is $0.93$ and for Chloride it is $3.16$. We see that:
$3.16 - 0.93 = 2.23$

Giving an ionic bond.

An easy way to see what atoms rather would form ionic bonds is to identify its position in the ptable. If its a metal it would have a low electronegativity and if its an halogen it would have a high electronegativit.
