WebBoron is a chemical element with atomic number 5 which means there are 5 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom … WebThe problem is that you will also record lines for the unfragmented Cl 2 + ions. Think about the possible combinations of chlorine-35 and chlorine-37 atoms in a Cl 2 + ion. Both atoms could be 35 Cl, both atoms could be 37 Cl, or you could have one of each sort. That would give you total masses of the Cl 2 + ion of: 35 + 35 = 70. 35 + 37 = 72
