The electrons identified by the following quantum numbers `n` and `l: (i) n = 4, l = 1, (ii) n = 4, l = 0, (iii) n = 3, l = 2`, and (iv) `n = 3, l = 1` can be placed in the order of increasing enegry from the lowest to the highest as

Options

A. (iv) lt (ii) lt (iii) lt (i)
B. (ii) lt (iv) lt (i) lt (iii)
C. (i) lt (iii) lt (ii) lt (iv)
D. (iii) lt (i) lt (iv) lt (ii)

Answer

A

Explanation

Higher is the value of `(n+l)` more is the energy level of orbital. If `(n+l)` is same lower value of n decides lower energy level.
