Question

An electron is in one of the 3d – orbitals. What are the possible values of n, l and m for this electron?

• A. n = 3, l = 0, $m_{l} = 0$
• B. n = 3, l = 1, $m_{l}$= - 1, 0, +1,
• C. n = 3, l = 2, $m_{l}$= - 2, -1,0,+1,+2
• D. n = 3, l = 3, $m_{l}$ = - 3, -2, -1, 0, +1, +2, +3

Answer 1

Answer: (C)

n = 3, l = 2, $m_{l}$= - 2, -1,0,+1,+2

Answer 2

: For 3d, n = 3, l = 2, $m_{l}$ = -2, -1, 0, + 1, +2
