The electrostatic attraction between oppositely charged ions.

Name the elements needed for Ionic bonding.

What charge of ions are used in ionic bonding?

High melting points, High boiling points, Mostly soluable, Can conduct electricity when the ions are mobile, melted or dissolved 

Lots of energy is needed to overcome the strong ionic bonds. So it makes them hard to melt and boil.

Why do Ionic compounds have high melting and boiling points?

In an ionic bond, a metal atom is transfer electrons to a non- metal atom.
