Which of the following arrangement is possible? array llll n & l & m & s array

Options

  1. A5 2 2 +1 / 2
  2. B2 2 0 -1 / 2
  3. Carray llll 3 & -2 & 1 & +1 / 2 array
  4. D0 0 1 +1 / 2

Correct answer

A. 5 2 2 +1 / 2

Step-by-step solution

For a given value of n, l=0 to n-1 ; for a given value of l, m=-l to +l including zero; for a given value of m, s=+ 1 2 ,- 1 2 When n=5 , then l=0,1,2,3,4 ; when l=2 , then m=-2,-1,0,+1,+2 The value of s can be 1 / 2 Hence, the arrangement, n=5, l=2, m=2 , s=+1 / 2 is possible for an electron.
