Correct answer: C. 3, 0, 0, +1/ 2
- A. 2, 0, 0, +1/ 2
- B. 3, 2, 1, +1/ 2
- C. 3, 0, 0, +1/ 2
- D. 3,1, 2, +1/ 2
Explanation
Principal Quantum Number (n): 3 (Third energy level) Azimuthal Quantum Number (ℓ): 0 (s orbital) Magnetic Quantum Number (mℓ): 0 (One of the orientation states within the s orbital) Spin Quantum Number (ms): +1/2 (Spin orientation)

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.
