It depends on the isotope of Zinc that you are considering. The most common isotope is Zn-64 (atomic number: 30). The nucleus consists of 30 protons and 34 neutrons with 30 electrons. One school of thought derives the number of neutrons from the periodic table as below. The number of protons = the number of electrons Fill in the missing spaces in the charts below.

Zinc (2+) is a divalent metal cation, a zinc cation and a monoatomic dication. It has a role as a human metabolite and a cofactor. Zinc cation is a Copper Absorption Inhibitor. The physiologic effect of zinc cation is by means of Decreased Copper.

Number of protons neutrons electrons in zinc
  • Zinc is a transition earth metal with atomic number 30 and represented in the Periodic Table with the symbol ‘Zn’. Electron configuration: Ar 3d 10 4s 2. Abrrivated electronic configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10. Valence electrons. The electrons in the outermost or highest energy level orbitals. Hence, valence electrons in.
  • For the fourth period/row, all of these electrons build the third shell to a maximum of 18 electrons. Remember that the first eight were placed during our trip through the third period/row. The fourth row of the periodic table has transition metals ranging from scandium (21) to zinc (30).
