Read each question carefully and provide the best answer. For formula writing, ensure correct subscripts and charges. For naming, use IUPAC nomenclature rules.
Ionic bonds are formed between a metal and a nonmetal, involving the transfer of electrons. This transfer results in the formation of ions (cations and anions) which are held together by electrostatic forces. The overall charge of an ionic compound must be neutral.

1. Ionic compounds are formed between a and a .
2. The transfer of electrons results in the formation of positively charged ions called and negatively charged ions called .
3. The overall charge of an ionic compound must always be .
