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

Options

A. Pauli's exclusion principle
B. Heisenberg's uncertainity principle
C. Hund's rule of maximum multiplicity
D. Aufbau principle

Answer

B

Explanation

Werner Heisenberg'a German physicist in 1927, stated uncertainty principal which states that it is impossible to determine simultantously, the exact position and exact momentum of an electron.
Mathematically, `Deltax xx Deltap ge (h)/(4pi)`
The important implications of the Heisenberg uncertainty principal is that it rules out existence of definite paths or trajectories of electrons and other similar particles
