When one atom donates an electron to another atom, the donating atom becomes a charged ion, and the receiving atom becomes a charged ion. these ions are joined together by a/an chemical bond.

The donating atom becomes a positively charged ion as it now has more protons than electrons.

The receiving atom becomes a negatively charged ion as it has more electrons than protons.

They are joined by an ionic bond.
