Read each question carefully and write the correct chemical formula for the given ionic compound. Remember to balance the charges to achieve a neutral compound.
Ionic compounds are formed between a metal and a nonmetal through the transfer of electrons, resulting in the formation of ions. Cations are positively charged ions, and anions are negatively charged ions. The chemical formula for an ionic compound represents the simplest whole-number ratio of ions that results in a neutral compound.
1. An ionic compound is formed between a and a .
2. Cations are charged ions, while anions are charged ions.
3. The overall charge of an ionic compound must always be .
