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.
The idea, in English
Atoms lose electrons to become positive ions (cations) or gain electrons to become negative ions (anions); the charge equals electrons lost or gained.
Explain in Egyptian Arabic
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.
