Which of the following is an incorrect set of quantum members?

Which of the following is an incorrect set of quantum members?

Options

  1. An=2,l=0,m=0n = 2, l = 0, m = 0
  2. Bn=1,l=0,m=0n = 1, l = 0, m = 0
  3. Cn=3,l=3,m=0n = 3, l = 3, m = 0
  4. Dn=2,l=1,m=1n = 2, l = 1, m = 1

Correct answer

C. n=3,l=3,m=0n = 3, l = 3, m = 0

Step-by-step solution

Maximum& l& value should be equal to& n−1& and it cannot be equal to& n.

∵∵ for (l)( l ) It can be upto (n−1)( n - 1 ) and

Thus, m=±lm = \pm l i.e. +l,0,−l+ l, 0, - l

for (a) n=2,l=0,m=0n = 2, l = 0, m = 0 (correct),

for (b) n=1,l=0,m=0n = 1, l = 0, m = 0 (correct),

(c) n=3,l=3n = 3, l = 3 (not correct),

(d) n=2,l=1,m=1n = 2, l = 1, m = 1& (correct),
