Asked in Premeth Test 18 — Alkyl Halides, Aldehydes and Ketones, Atomic Structure (20 March 2025) 2025Moderate

the maximum number of electron that in orbital can accommodate is/ are

Correct answer: C. 2

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Explanation

This option is incorrect because all orbitals, by definition, have the capacity to hold at least one electron. This option is incorrect because, as mentioned earlier, the maximum number of electrons that an orbital can hold is 2. The answer is 2. According to the Pauli exclusion principle, each orbital can accommodate a maximum of 2 electrons with opposite spins. This option is incorrect because it exceeds the maximum capacity of an orbital. As explained above, the maximum number of electrons an orbital can hold is 2 due to the Pauli exclusion principle.

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.
