ATOMIC WEIGHTS OF THE ELEMENTS 2019. These tables are based on the 2015 table with changes from the 2015 table for the values of aluminium, argon, cobalt, gold, holmium, iridium, manganese, niobium, praseodymium, protactinium, rhodium, terbium, thulium and yttrium. See report 5 June 2018. The revised value of hafnium was reported 11 December 2019.

Most heavy metals have a high atomic number, atomic weight and a stål är ett exempel på en legering mellan järn, krom och nickel.
One atomic mass unit is equal to 1.66 x 10-24 grams. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article.

The official atomic weight or relative atomic mass of iron is 55.845(2). The bracketed figure reflects the uncertainty of the measurement. The reason for the uncertainty and the fact that iron is not a whole number is that terrestrial iron is made up of a number of isotopes and its relative atomic mass varies, depending on the relative concentration of each isotope in the sample.
