Question

If a sub-shell is denoted as 2p then its magnetic quantum number values are _______, ________, ________.

• A. -3, -2, -1
• B. -1, 0, +1
• C. -2, -1, 0
• D. 0, 1, 2

Answer 1

Answer: (B)

-1, 0, +1

The magnetic quantum number associated with n = 2 (i.e. l = 1) for 2p will be

$-1,0,+1$.

This is because the value of $m$ ranges from $-lto+l$

Thus option B.
