The chemical bond that occurs when atoms lose, gain, or share electrons is called a chemical bond.

Here's a breakdown of the types of chemical bonds:

* Ionic Bonds: Occur when one atom loses electrons (becoming a positively charged ion, or cation) and another atom gains those electrons (becoming a negatively charged ion, or anion). The opposite charges attract, forming a strong bond.

* Covalent Bonds: Occur when atoms share electrons. The shared electrons are attracted to the nuclei of both atoms, holding them together.
