Periodic Table with Atomic Mass

This is a periodic table with atomic mass, element name, element symbol, and atomic number. The atomic mass is the average number of protons and neutrons in atoms of a chemical elements, allowing for the natural abundances of the element’s isotopes. This table uses the latest accepted single values because it makes chemical calculations easier. The IUPAC actually recommends a range of atomic mass values for most elements because the isotopic ratio isn’t a constant everywhere on Earth.
