Which type of chemical combination involves the transfer of electrons from one atom to another, resulting in the formation of oppositely charged ions?
Ionic bonding
Hydrogen bonding
Covalent bonding
Metallic bonding
Explicaţie
Ionic bonding occurs between a metal and a non-metal. The metal atom donates one or more electrons to the non-metal atom, resulting in the formation of positively charged cations and negatively charged anions. These oppositely charged ions are held together by electrostatic forces to form an ionic compound.
