The 'm' quantum number describes the _ of an electron.
Correct answer: C. Orientation of orbital
- A. Energy level
- B. Orbital or subshell
- C. Orientation of orbital
- D. Spin
Explanation
'n' is the Principal Quantum Number that represents the different energy levels. 'l' is the Azimuthal Quantum Number which represents the different subshells. 's' is the Spin Quantum Number which represents the different spin directions of an electron while moving in an orbital. 'm' is the Magnetic Quantum Number that represents the orientation of the orbital.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
