(i) n = 5 means 1= 0,1,2,3,4 sincem = + 1 hence total no. of electrons will be =0 (from s) + 2 (fromp) + 2 (fromd) + 2 (from f) + 2 (from g) = 0 + 2 + 2 + 2 + 2 = 8 (ii) n=2, l=1,

m_{t} = 1, m_{s} =

1/2 represent
2p orbital with one electron

Q. Given (A) n=5,mℓ​=+1 (B) n=2,ℓ=1,mℓ​=1,ms​=−1/2 The maximum number of electron(s) in an atom that can have the quantum numbers as given in (A) and (B) are respectively:

(i) n = 5 means 1= 0,1,2,3,4 sincem = + 1 hence total no. of electrons will be =0 (from s) + 2 (fromp) + 2 (fromd) + 2 (from f) + 2 (from g) = 0 + 2 + 2 + 2 + 2 = 8 (ii) n=2, l=1, mt​=1,ms​= 1/2 represent 2p orbital with one electron

Q. Given
(A) $n = 5, m_{ℓ} = + 1$
(B) $n = 2, ℓ = 1, m_{ℓ} = 1, m_{s} = - 1/2$
The maximum number of electron(s) in an atom that can have the quantum numbers as given in (A) and (B) are respectively:

(i) n = 5 means 1= 0,1,2,3,4 sincem = + 1 hence total no. of electrons will be =0 (from s) + 2 (fromp) + 2 (fromd) + 2 (from f) + 2 (from g) = 0 + 2 + 2 + 2 + 2 = 8 (ii) n=2, l=1, $m_{t} = 1, m_{s} =$ 1/2 represent
2p orbital with one electron
