Irregularities Of Mass In The Periodic Table

Irregularities Of Mass In The Periodic Table. Elements do not have their atomic masses as whole numbers. The atomic mass of an element is the weighted average of all the different isotopes of that element This is also known as Relative Mass. Calculating Relative Mass.
