Atoms with 3 or fewer electrons in their outer energy level are classified as monatomic atoms. This means that the atom is composed of a single atom and does not have any electron bonds to other atoms. Because of this, monatomic atoms are the most stable and do not form compounds. These atoms are also the smallest and lightest due to the lack of electron bonding. Examples of monatomic atoms are hydrogen, helium, and lithium.
