In the periodic table, period 4 elements have atomic numbers ranging from 19 (potassium) to 36 (krypton). The element with the lowest mass in period 4 is potassium (K), which has an atomic number of 19 and an atomic weight of approximately 39.1 atomic mass units.
Magnesium is a meta element. Atomic mass of it is 24.
Short answer: boron. Long answer: any element with 11 protons or less could theoretically have an atomic mass of 11, as the mass = Number of Protons + Neutrons, if you add/take a certain number of neutrons from the atom it will be able to have an atomic mass of 11, but some aren't possible and others are too unstable, and will decay instantly.
The Atomic Mass usually increases, but there are a few exceptions, such as tellurium to iodine.
