The unique integer assigned to each element, known as the

between the frequency and the relative mass of each atom. Let’s rank the
elements by atomic mass, and allocate an integer to each rendering to its
ranking in order by mass. In the Periodic Table, this rank order number also agrees
to the element’s position in the Periodic Table.
