Two electrons occupying the same orbital are distinguished by
Correct answer: C. Spin quantum number
- A. Magnetic quantum number
- B. Azimuthal quantum number
- C. Spin quantum number
- D. Principal quantum number
Explanation
The correct answer is the spin quantum number. This quantum number, represented as either +1/2 or -1/2, allows for the differentiation between two electrons occupying the same orbital, as no two electrons can have identical sets of quantum numbers within an atom due to the Pauli exclusion principle. Magnetic quantum number describes the orientation of the orbital, not the electrons within it. Azimuthal quantum number defines the shape of the orbital, not electron-specific properties. Principal quantum number indicates the energy level and does not account for differences in electron spin within the same orbital.

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.
