Isotopes and Mass Number

Isotopes and Mass Number. Leon the Electron. Jimmy Neutron. Atomic Number. The number of protons in each atom identifies it as an atom of a particular element Each atom has a unique number of protons and, in effect, the number of protons cannot change for a particular atom
