1. a type of covalent bond where electrons are shared unequally
2. the tendency of an atom to attract electrons towards itself
3. a bond that forms between an electronegative atom and a hydrogen atom with a positive dipole
4. a type of covalent bond where electrons are shared equally

1. polar covalent bond

2. electronegativity

3. hydrogen bonding

4. nonpolar covalent bond

Explanation:

1. A type of covalent bond where electrons are shared unequally. polar covalent bond. In this kind of bond, there is a negative charge density over the more electronegative atom and a positive charge density over the less electronegative atom.

2. The tendency of an atom to attract electrons towards itself. electronegativity. Atoms with higher electronegativity have a higher tendency to attract electrons towards itself.

3. A bond that forms between an electronegative atom and a hydrogen atom with a positive dipole. hydrogen bonding. This is an especially strong kind of dipole-dipole interaction.

4. A type of covalent bond where electrons are shared equally. nonpolar covalent bond. Atoms have the same (or similar) electronegativity so the electrons are shared equally.
