Definitions:

Hydrogen Bonds

A type of weak chemical bond that is formed when the slightly positive hydrogen atom of one molecule is attracted to the slightly negative atom of another molecule, such as oxygen or nitrogen.

Polar Covalent

A type of chemical bond where electrons are unequally shared between atoms, resulting in partial electrical charges.

Nonpolar Covalent

A type of chemical bond where two atoms share a pair of electrons equally, typically between atoms of similar electronegativity.

Negatively Charged

describes an object or particle that has more electrons than protons, resulting in a net negative electric charge.
