P-chem

The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mass is also known as atomic weight (symbol: A r ). Phosphorus (P) has an atomic mass of 15.
