Front

A molecule with an uneven distribution of electron density, leading to partial positive and negative charges.

Back

Polarity / Polar molecule

Front

A molecule in which the electrons are evenly distributed, resulting in no partial charges.

Back

Nonpolar molecule

Front

Back

Partial charge

Front

A measure of a fluid's resistance to flow.

Back
