Front

What is the relationship between metals and nonmetals in ionic bonding?

Back

In ionic bonding, metals lose electrons to form cations, while nonmetals gain electrons to form anions, resulting in electrostatic attraction between them.

Front

What type of bond is formed by the transfer of electrons?

Back

Ionic bonds are formed by the transfer of electrons between metals and nonmetals.
