The type of bond that forms when electrons are given or gained is called an ionic bond.

Here's why:

* Ionic bonds form between metals and nonmetals.

* Metals tend to lose electrons, becoming positively charged ions (cations).

* Nonmetals tend to gain electrons, becoming negatively charged ions (anions).

* The electrostatic attraction between these oppositely charged ions holds them together in a strong ionic bond.
