Question

In terms of ionisation enthalpy and electron gain enthalpy, what type of atoms combine to form an ionic compound?

Answer 1

Ionic bonding usually involves a metal and a non metal. The metal becomes a cation (positively charged ion) by losing the electrons in its outer shell, and the non metal gains these electrons to become an anion, a negatively charged ion. By this process, both elements gain a full outer shell through the transfer of electrons from the metal to the non metal.

Hope that helps!

Answer 2

Answer:

elements with low ionisation enthalpy and elements with high electron gain enthalpy combine to form ionic compound
