Quantum number values for 3p orbitals are____________________?
Correct answer: C. n=3 l=1
- A. n=3 l=2
- B. n=3 l=0
- C. n=3 l=1
- D. n=3 l=3
Explanation
A p subshell always has the azimuthal quantum number l = 1, and the number 3 indicates the principal quantum number n = 3. Thus a 3p orbital has n = 3 and l = 1. The likely error is selecting l = 2, which belongs to a 3d subshell, or l = 0, which belongs to 3s.

About Quantum Numbers
Quantum numbers describe an electron's energy level, subshell, orbital orientation and spin. You examine the principal, azimuthal, magnetic and spin quantum numbers, their allowed values, orbital capacity and how they determine electronic configurations and distinguish electrons within an atom.
