Question

For the simple cubic crystal described above, i.e. a = 0.7\: nma=0.7nm, calculate the surface density of atoms (i.e. number of atoms per unit area) on the (100) plane in unit of cm^{-2}cm
−2
. Values within 5% error will be considered correct.

Answer 1

Answer:

2.0408163e+14

Explanation:

number of atom=1/4*4=1

surface density= number of atom /area of the surface

1/(0.7*10^-7)^2

will give you the ans

* area formula--- (s)^2              (s=0.7nm) GIVEN

* in order to convert nm to cm we have to multiply by 10^-7
