Description

Ionic Bonding

Ionic bonds are formed when metals transfer electrons to non-metals, resulting in the formation of ions. For example, sodium (Na) loses an electron to become Na+, while chlorine (Cl) gains an electron to become Cl-.

a
State the charge of a sodium ion after it loses an electron.
