Which of the following is responsible to rule out the existence of definite paths or trajectories of electrons?

A

Pauli’s exclusion principle

B

Heisenberg’s uncertainty principle

C

Hund’s rule of maximum multiplicity

D

Text Solution

Verified by Experts

The correct Answer is:
B
Werner Heisenberg, a German physicist in 1927, stated uncertainty principle which states that it is impossible to determine simultaneously, the exact position and exact momentum of an electron.
Mathematically, `DeltachixxDeltapgeh/(4pi)`
The important implications of the Heisenberg uncertainty principle are that it rules out existence of definite paths or trajectories of electrons and other similar particles.
