Definitions:

Ionic Bonding

A chemical bond formed between two atoms when one atom donates an electron to another, creating ions that attract each other due to opposite charges.

Polar Covalent

A type of chemical bond where electrons are unevenly distributed, resulting in a partial positive and negative charge on different atoms.

Nonpolar Covalent

A type of chemical bond where two atoms share a pair of electrons equally, resulting in no charge separation.

Lewis Structure

A graphical representation of the valence shell electrons in molecules or ions, showing how electrons are shared between atoms to form bonds.
