Question

Q3. Which of the following is responsible to rule out the existence of
definite paths or trajectories of electrons?
(a) Pauli's exclusion principle.
(b) Heisenber's uncertainty principle. V
Hund's rule of maximum multiplicity.
(d) Aufbau principle.​

Answer 1

Answer:

D Aufbau principle states that electrons first occupy the lowest energy orbital available to them and enter into higher energy orbitals only after the lower energy orbitals are filled. Therefore Heisenberg's uncertainty principle is responsible to rule out the existence of definite paths or trajectories of electrons.
