Calculate the number of particles in an isotope of Gold-190 Electron: Neutron: Proton:?

Gold is Au in the periodic table. The table shows proton numbers, the typical m in a sample, and the transition category it is naturally found in, such as metal. An isotope is an element with a different number of neutrons, but always the same protons. Naturally occurring gold comes in Au-197. Because of this restriction, we know Au-190 has 79 protons and 121 neutrons. Unless the metal is ionized (loss or gain of electrons), the material will be electrically neutral. This means it must contain the exact number of protons (positive charge) as electrons. So, Electrons = 79.
