Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of zinc-65 (atomic number: 30), - 2ACT1EY from Alamy's library of millions of high resolution stock photos, illustrations and vectors. The density of zinc: Effective number of atoms in unit cell of HCP, n=6. using the relation $\rho = \frac{nM}{N_A \times V}$, we have $[where \hspace{0.3cm}n = 6, M = 65.37 (given), N_A = 6.0238 \times 10^{36}]$ $\rho = \frac{6 \times 65.37}{6.0238 \times 10^{26}\times 9.35 \times 10^{-29}} \approx 6964kg/m^3$ Atomic Packing Factor: Now, c=1.633 a Zinc has the symbol Zn.. Atomic Number = 30, Atomic Mass = 65.39, 30 protons, 30 electrons, 35 neutrons. First isolated by. Most common uses: The alloy brass contains copper and anywhere from 20-45% of zinc, depending upon the type of brass.
