Which of the following sets of quantum numbers is incorrect for an electron?
Correct answer: C. n= 3, l=5 ,m=2
- A. n=2,1=0, m=0
- B. nm23, 0=1, =1
- C. n= 3, l=5 ,m=2
- D. n=4, t=, m=2

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.
