Atoms join together to form compounds by gaining losing or sharing

electrons

Explanation:

Some electron arrangements are more stable than others, which is why atoms often gain, lose, or share electrons with other atoms. This transfer or sharing of electrons forms chemical bonds that unite atoms in compounds.
