The atomic weight of gold is the other number next to it. b. Discovery of Protons The presence of positively charged particle in an atom had been first observed in 1886 by E. Goldstein based on the concept that atoms are electrically neutral i.e., it has same number of positive and negative charge. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. The protons and neutrons are found in the nucleus, while the electrons are located outside the nucleus in orbitals. What's Iron's mass number?
