How many neutrons does zinc has?
34, 36, 37, 38, and 40.
The most stable isotope of zinc is Zn-65, with 35 neutrons
There are 30 protons and 35 neutrons. This is true of the isotope Zinc-65 only. This isotope is produced synthetically. There are a total of seven zinc isotopes, five of which occur naturally and two that are synthesized. 64Zn has 34 neutrons 65Zn has 35 neutrons and is synthetic 66Zn has 36 neutrons 67Zn has 37 neutrons 68Zn has 38 neutrons 70Zn has 40 neutrons 72Zn has 42 neutrons and is synthetic
All atoms of zinc contain 30 protons, but the number of neutrons in an atom may vary. Atoms with the same number of protons but different numbers of neutrons are called "isotopes." The most common isotope of zinc is Zn-64, which has 34 neutrons. Other naturally occurring isotopes of zinc may have 35, 36, 37, or 39 neutrons.
