Options

  1. AZeeman effect
  2. BPauli's exclusion principle
  3. CStark effect
  4. DHeisenberg principle

Correct answer

B. Pauli's exclusion principle

Step-by-step solution

Pauli's exclusion principle is, "No two electrons in an atom can have the same set of all four quantum numbers". e.g. for (4 s^2 ) configuration, its ( aligned & 1st e⁻= array lllc n & l & m & s & 0 & 0 & +1 / 2 array & 2nd e⁻=4 0 0 0 -1 / 2 & aligned )
