An element occuring in the bec structure has 12.08 × 1 0 23 unit cells. The total number of atoms of the element in these cells will be

There are two atoms in a b cc unit cell. So, number of atoms in 12.08 × 1 0 23 unit cells = 2 × 12.08 × 1 0 23 = 24.16 × 1 0 23 atoms.

An element occuring in the bec structure has $12.08 \times 1 0^{23}$ unit cells. The total number of atoms of the element in these cells will be

Options:

Answer:

Solution:

There are two atoms in a $b cc$ unit cell. So, number of atoms in $12.08 \times 1 0^{23}$ unit cells $= 2 \times 12.08 \times 1 0^{23} = 24.16 \times 1 0^{23}$ atoms.
