Ionic Compounds and the Formation of Ionic Bonds

Ionic bonds result from the sharing of electrons between atoms.

• TRUE

• A charged particle formed by gaining or losing electrons

• A particle with no valence electrons

How are cations and anions formed in ionic bonding?

• Metals gain electrons, nonmetals lose electrons

• Metals lose electrons, nonmetals gain electrons

• Both metals and nonmetals lose electrons
