the periodic table has a over 100 elements and each element has a atomic number and a atomic mass.the atomic mass is the number that states how many atoms are there in all.the atomic number is the number that states how many protons and electrons are in the element.so for example the element oxegens atomic mass is 16 and the atomic number is 8.the best way of thinking about it is:atomic mass=nuetrons protons and electrons/and the atomic#=the protons and electrons.most of the time the atomic# is half of the atomic mass or really close to it if the atomic mass is not an even #.over all there similar becuase there the numbers that make up the element.
