Types of Bonds

In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.

• electrons are completely transferred between two metals.

• pairs of electrons are shared between two nonmetal atoms.

• two nonmetal atoms are attracted to each other by opposite charges.
