Incorrect set of quantum numbers from the following is

Options

  1. An =4, l =2, ~m _ l =-2,-1,0,+1,+2, ~m _ s =-1 / 2
  2. Bn =5, l =3, ~m _ l =-3,-2,-1,0,+1,+2,+3, ~m _ s =+1 / 2
  3. Cn =4, l =3, ~m _ l =-3,-2,-1,0,+1,+2,+3, ~m _ s =-1 / 2
  4. Dn =5, l =2, ~m _ l =-2,-1,+1,+2, ~m _ s =+1 / 2

Correct answer

D. n =5, l =2, ~m _ l =-2,-1,+1,+2, ~m _ s =+1 / 2

Step-by-step solution

For any value of I , m₁ value will be - l to + I So for n =5 and I =2 : m _ l =-2,-1,0,+1,+2 and m _ s =+ 1 2 or - 1 2 Hence, the set n=5, l=2, m_l=-2,-1,+1,+2, m_s=+ 1 2 is incorrect
