What 2 numbers are shown in tye periodic table for each element?
The number above the symbol is the atomic number, or the number of protons in the nucleus of one atom of the element. It is this number by which they organized the periodic table. If this number changes so does the identity of the element. In a balanced atom this number will also be the number of electrons in the electron cloud. The number below is the atomic mass number, or the average number of particles (protons plus neutrons) in the nucleus. Since the number of neutrons can change this number must be given as an average so it may contain a decimal.
