This document presents the IUPAC Periodic Table of the Elements from 2013. It lists the name, symbol, and standard atomic weight for each element in order of increasing atomic number from hydrogen (1) to lawrencium (103). Some elements have a range or uncertainty listed for their atomic weight. The table also notes alternative spellings for some elements and indicates that claims for the discovery of elements 113, 115, 117, and 118 have not yet been assigned. It is copyrighted by IUPAC.
