Naturally occurring zinc (Zn) is composed of the 5 stable isotopes 64Zn, 66Zn, 67Zn, 68Zn, and 70Zn with 64Zn being the most abundant (48.6% natural abundance). Twenty-one radioisotopes have been characterised with the most abundant and stable being 65Zn with a half-life of 244.26 days, and 72Zn with a half-life of 46.5 hours. All of the remaining radioactive isotopes have half-lives that are less than 14 hours and the majority of these have half lives that are less than 1 second.

How many protons does zinc (zn) have?
Zinc has 30 protons.
Why does ZnOH2 Dissolve in excess OH?
The formation of the soluble Zn(OH)4- ion (tetrahydroxidozincate ion)
What is the most common isotope of uranium?
The most common isotope of zinc is the one with mass number 64; the atomic number of zinc is 30, which means each zinc nucleus contains 30 protons, and the mass number is defined as the sum of the numbers of neutrons and protons. Therefore, the number of neutrons is (64 - 30) or 34.
Atomic number of 30 and 34?
The atomic number of an element is the number of protons in an atom's nucleus. Element with an atomic number 30 is Zinc (Zn), while element with an atomic number 34 is Selenium (Se).
What would an atom Zn become if it gained a proton?
If an atom of zinc (Zn) gained a proton, it would become a different element altogether due to the change in the number of protons. Since the number of protons determines the element's identity, adding a proton would change its atomic number and transform it into a new element.
