    @some_someone Your first answer was right. I'm looking at your second answer now. When we look at elements on the Periodic Table, we see two different numbers: Atomic NUMBER and Atomic MASS. The ATOMIC NUMBER is the number of PROTONS/ELECTRONS. The ATOMIC MASS is the number of PROTONS AND NEUTRONS, TOGETHER. If two atoms have different numbers of NEUTRONS, they're not going to have the same atomic mass.
