The value of the Principal quantum number "n" represents?
Correct answer: D. All of these
- A. The energy of an electron
- B. The location of an electron
- C. The size of an orbital
- D. All of these
Explanation
The principal quantum numbers tells us about, energy level, location of electrons as well as size of 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.
