Finding the number of Neutrons; Find first the mass number of each element. Zinc (atomic symbol: Zn, atomic number: 30) is a Block D, Group 12, Period 4 element with an atomic weight of 65.38. The number of electrons in each of zinc's shells is 2, 8, 18, 2, and its electron configuration is [Ar] 3d 10 4s 2 .

Changes in radiation given off by the radioactive isotope can be followed to find patterns in the way the alloy wears out. Zinc-65 can also be used to study the role of zinc in the human body.

Main Isotopes of Zinc. Five stable isotopes of zinc occur in nature, with 64 Zn being the most abundant isotope (49.17% natural abundance). Zinc-64 is composed of 30 protons, 34 neutrons, and 30 electrons. Zinc-66 is composed of 30 protons, 36 neutrons, and 30 electrons. 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.

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.

Zinc-65 can also be used to study the role of zinc in the human body. A person can be fed food that contains a small amount of zinc-65. Therefore, every isotope of zinc contains 30 protons. The superscript in the notation indicates the mass number of 65. By subtraction, the number of neutrons must be: The production of Mn 54 and Zn 65 from copper has been measured radiochemically at various depths and radial distances inside thick targets (up to 1 meter in size) that had been irradiated with 0.45‐Gev, 1.0‐Gev and 3.0‐Gev protons.
