It is defined as the average mass of atoms of an element, which is calculated with the help of relative abundance of isotopes of a naturally occurring element. For example, the atomic mass of hydrogen is 1.0079 and carbon is 12.011. Atomic Number Atomic number is defined as the number of protons in an element.

The first periodic table to become generally accepted was that of the Russian chemist Dmitri Mendeleev in 1869: he formulated the periodic law as a dependence of chemical properties on atomic mass. Because not all elements were then known, there were gaps in his periodic table, and Mendeleev successfully used the periodic law to predict ...

The truth is that atomic weights have changed as a function of time. Since 1899 the IUPAC Commission on Isotopic Abundances and Atomic Weights ( CIAAW) has been evaluating atomic weights and abundances. For example, Carbon had an atomic weight of 12.00 in 1902 but today it is [12.0096, 12.0116]!
