Since 1899 the iupac commission on isotopic abundances and atomic weights has been evaluating atomic weights and abundances. For example carbon had an atomic weight of 12 00 in 1902 but today it is 12. The periodic table also known as the periodic table of elements arranges the chemical elements such as hydrogen silicon iron and uranium according to their recurring properties.
The number of each element corresponds to the number of protons in its nucleus which is the same as the number of electrons orbiting that nucleus. Use this periodic table for calculating molar mass for any chemical formula. Options for hiding the symbol or name of the elements provide a handy learning aid for memorizing the periodic table.
