Hydrogen Bonds

Weak bonds between partially positive hydrogen atoms and partially negative atoms (such as oxygen or nitrogen) in different molecules or within the same molecule.

Atomic Mass

The mass of an atom, typically expressed in atomic mass units (amu), representing the total mass of protons, neutrons, and electrons in the atom.

Ionic Bond
