Question

The postulate of the Bohr Atomic model is given below. Arrange them in the correct sequence.

• A. 1,3,4,5,2
• B. 2,3,5,1,4
• C. 2,5,3,1,4
• D. 2,1,4,3,5

Answer 1

The correct option is C

2,5,3,1,4

The correct sequence of the postulate of the Bohr Atomic model is

1. Electrons revolve around the nucleus in a specified circular path called orbits or shells
2. Each orbit or shell is associated with a definite light amount of energy hence these are also called energy levels and are designated as K, L, M, and N respectively
3. The energy associated with a certain energy level increases with the increase of its distance from the nucleus.
4. The electron revolves in a particular Orbit the electron does not lose its energy therefore these Orbits are called stationary orbits and the electrons are said to be stationary energy state.
5. An electron jumps from a lower energy level to a higher energy level by absorbing energy but when it jumps from a higher to lower energy level energy is emitted in the form of electromagnetic radiation.

Conclusion Statement: Option (c) is the correct answer.
