What is the electron configuration of a typical nonmetal?

Back

A typical nonmetal has a high electronegativity and tends to gain electrons to achieve a stable electron configuration.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
