Periodic Table of Elements
... • On the periodic table, the average mass of the atoms in an element is expressed as the atomic mass. • Adding the protons and neutrons will give you the atomic mass. • For example Iron (Fe) has an atomic mass of 56 because there are 26 protons and 30 neutrons and added together that makes 56. ...

Dmitri Mendeleev
Dmitri Ivanovich Mendeleev (/ˌmɛndəlˈeɪəf/; Russian: Дми́трий Ива́нович Менделе́ев; IPA: [ˈdmʲitrʲɪj ɪˈvanəvʲɪtɕ mʲɪndʲɪˈlʲejɪf]; 8 February 1834 – 2 February 1907 O.S. 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.
