n and ℓ for four electrons are given as i n = 4 , ℓ = 1 ii n = 4 , ℓ = 0 iii n = 3 , ℓ = 2 iv n = 3 , ℓ = 1. Arrange them in order of increasing energy from the lowest to highest:

Lower the value of n + ℓ , lower is the energy. When n + ℓ value is the same for two orbitals, lower n value implies lower energy of the electron. Thus, the order will be: (iv) < (ii) < (iii) < (i).
