Q8
It is given that the atoms are stacked on top of each other as shown below.
Thus thickness of each atom equals the diameter of the atom twice the radius.
Diameter, D = 2* radius = 2* 134 pm = 268pm
We know that 1 pm equals 10-12 m.
Thus diameters in m = 268 pm * (10-12 m/pm)= 2.68 x 10-10 m
Thickness of Zinc, t = 0.0117712122 cm = 0.0117712122 cm * (0.01 m/cm) = 1.17712122 x 10-4 m
No. of Atoms, N will be given be,
Thus, the coating is 4.39 x 105 Zn atom thick.
given that the atomic radius of zinc is 134 pm, calculate the thickness of the zinc...
