WebIon – atom with an unequal number of PROTONS & ELECTRONS Stable – atom with equal PROTONS & ELECTRONS and also has a mass that matches the rounded mass from the Periodic Table *The mass of an atom is the SUM of its PROTONS & NEUTRONS. End of preview. Want to read all 2 pages? WebSo once again for protons, we look at the atomic number, that's 92. So there must be 92 protons. In a neutral atom, the number of electrons is equal to the number of protons. So there are 92 electrons and then finally, to figure out the number of neutrons, we subtract this number from the mass number. So we just need to do 235 minus 92. penn state hershey transfer
