How many protons, electrons, and neutrons are in an atom of zinc-65? Solution \[\text{number of protons} = 30\] For all atoms with no charge, the number of electrons is equal to the number of protons. \[\text{number of electrons} = 30\] The mass number, 65, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the Atomic Number of Zinc. Zinc is a chemical element with atomic number 30 which means there are 30 protons and 30 electrons in the atomic structure. The chemical symbol for Zinc is Zn. Atomic Mass of Zinc. Atomic mass of Zinc is 65.409 u.

Naturally occurring zinc (30 Zn) is composed of the 5 stable isotopes 64 Zn, 66 Zn, 67 Zn, 68 Zn, and 70 Zn with 64 Zn being the most abundant (48.6% natural abundance).Twenty-five radioisotopes have been characterised with the most abundant and stable being 65 Zn with a half-life of 244.26 days, and 72 Zn with a half-life of 46.5 hours.

Protonation is the addition of a proton to an atom, molecule, or ion. Protonation is different from hydrogenation in that during protonatio A proton is a subatomic particle that has a positive charge of +1 e.
