How is it represented on the copy of the Table that you are currently using?


The elements on the Periodic Table are characterized by their atomic number, #Z#, which value specifies the identity of the element. Beneath the prominently displayed elemental symbol (specific to #Z#), the relative atomic mass is printed, and this is the weighted average of the element's particular isotopic distribution. Usually the name of the element also appears.
