What happens when atoms do ionic bonding?

Ionic bonding is the complete transfer of valence electron (s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Answer: the metal loses electrons to become a positively charged cation

Explanation: the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
