Q. Which of the following pairs is not correctly matched?
(a) Hund’s rule In orbitals of equivalent energy electron spins remain unpaired if possible.
(b) Pauli’s exclusion principle No two electrons can have all the four quantum numbers identical.
(c) Zeeman effect The effect of magnetic field on the atomic spectra.
(d) Uncertainty principle It is impossible to determine the position of an electron.

Structure of Atom

Solution:

According to uncertainty principle, it is impossible to measure simultaneously the position and momentum of an electron with absolute accuracy.
