Which of the following arrangement is possible ?

Options

A. `{:(n, l, m, s),(5,2,2,+(1)/(2)):}`
B. `{:(n, l, m, s),(2,2,0,-(1)/(2)):}`
C. `{:(n, l, m, s),(3,-2,1,+(1)/(2)):}`
D. `{:(n, l, m, s),(0,0,1,+(1)/(2)):}`

Answer

A

Explanation

When n=5, then l=0,1,2,3,4.
Again when I=2, then m=-2,-1,0,+1,+2. The 's' value can be `pm` 1/2
Hence the arrangement , n=5, l=2,m=2, s=+1/2 is possible for an electron.
