Question

Which of the following statements do not form a part of Bohr’s model of hydrogen atom ?
(a) Energy of the electrons in the orbits are quantized
(b) The electron(s) in the orbit nearest to the nucleus has the lowest energy
(c) Electrons revolve in different orbits around the nucleus
(d) The position and velocity of the electrons in the orbit cannot be determined simultaneously.

Answer 1

(d) is uncertainty principle which was given by Hiesenberg and not Bohr’s postulate.

Hope my answer helps you!

Answer 2

Answer:

The option (D) is not a form of Bohr's hydrogen model atom.

Explanation:

This principle is based on the Heisenberg Uncertainty Principle which states that the “position and velocity” of an object can’t be measured at any point in time.  

Neil Bohr postulated the Bohr’s atomic model that stated as:

• The energy of the electrons in the orbits is quantized and this point became the predecessor of quantum mechanics.
• Electrons revolve in different orbits around the central nucleus.  
• The electrons orbit around the nucleus with orbits of different size and energy with the lowest energy being the one closest to the nucleus. It also stated that radiation of energy takes place when electrons move from “one orbit to another”.
