Question

If n and l are respectively the principal and azimuthal quantum numbers, then the expression for calculating the total number of electrons in any orbit is-

Options

A.2(2l + 1)
B.2(2l + 1)
C.2(2l + 1)
D.2(2l + 1)

Solution

Total number of electrons in an orbital  = 2 (2l +1).
The value of l varies from 0 to n - 1.
∴ Total numbers of electrons in any orbit =2(2l + 1).
