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.

What can be generalized about covalent bonds?

• Electrons will be exchanged.
• Electrons will be transferred.
• Electrons will be given and taken.
• Electrons will be shared.
