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.

When two nonmetals do not share electrons evenly, the resulting covalent bond will be

• nonpolar
• polar
• ionic
• metallic

The bond formed between atoms of the same element:

• nonpolar covalent
• polar covalent
• ionic bond
• hydrogen bond

In general, substances with stronger intermolecular forces have ________ boiling points than those with weaker forces

• Higher
• Lower
• Forces and boiling point are not related
