Ionic and Covalent Bonding

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when a metal donates electrons to a nonmetal.

Front

What is covalent bonding?

Back

Covalent bonding is the sharing of electron pairs between nonmetal atoms.
