Question

In how many elements the last electron will have the following set of quantum numbers, n = 3 and l = 1?

• A. 2
• B. 8
• C. 6
• D. 10

Answer 1

Answer: (C)

6

Answer 2

: n = 3, l = 1 represents 3p orbital. Since p has three orientations $p_{x},p_{y}$ and $p_{z,}$ 6 electrons will show same quantum number values of n and l.
