What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where two atoms share electrons equally, resulting in no charge separation.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom donates an electron to another atom, resulting in the formation of oppositely charged ions.
