Ionic compounds are formed between a metal and a nonmetal, or a polyatomic ion. They involve the transfer of electrons, resulting in the formation of ions that attract each other.
1. An ionic bond typically forms between a and a .
2. When atoms lose electrons, they form positively charged ions called .
3. When atoms gain electrons, they form negatively charged ions called .
4. The overall charge of an ionic compound must always be .
