1. Locate the element on the Periodic Table.
2. Find the element’s atomic number (which is the same as the number of protons)
3. Find the element’s atomic weight.
4. Round off the atomic weight to the nearest whole number to find the Atomic Mass.
5. Subtract the atomic number from the atomic mass (The numbers after the decimal point represent the usually very small mass of the electrons in the atom.)
