Atomic mass
Atomic number:- the number of a chemical element in the periodic table of Mendeleev- a number equal to the number of protons in the atomic nucleus- a number equal to the number of electrons in the neutral atomRelative atomic mass: the mass of an isotope expressed in atomic mass units(1 amu= 1/12 atomic mass of the isotope 12C).For chemical elements the term atomic weight is reccomended by IUPAC.
