What elements generally make a covalent bond?

• metal and nonmetal
• 2 nonmetals
• metal
• none of the above

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.
