Question

If n is the number of an atomic shell, then the maximum number of electrons that can be accommodated in nth shell according to Bohr-Bury scheme is

• A.
  $\frac{n}{2}$
• B.
  $\sqrt{2}n$
• C.
  $2n^2$
• D.
  $2n^3$

Answer 1

The correct option is C

$2n^2$
The maximum number of electrons which can be put in a particular energy level or shell was given by the Bohr-Bury scheme. According to this scheme, the maximum number of electrons which can be accommodated in any energy level of the atom is given by $2n^2$, where n is the number of that energy level, 1, 2, 3, …

Hence, the correct answer is option (c).
