# Ions (cations and anions)

> Atoms lose electrons to become positive ions (cations) or gain electrons to become negative ions (anions); the charge equals electrons lost or gained.

> [ar-EG] الذرة بتفقد electrons فتبقى positive ion (cation)، أو بتكسب electrons فتبقى negative ion (anion). والـ charge بتساوي عدد الـ electrons اللي الذرة فقدتها أو كسبتها.
