Given below are two statements Statement I : According to...
Given below are two statements
Statement I : According to Bohr’s model of hydrogen atom, the angular momentum of an electron in a given stationary state is quantised.
Statement II : The concept of electron in Bohr’s orbit, violates the Heisenberg uncertainty principle. In the light of the above statements, choose the most appropriate answer from the options given below
Options
- AStatement is incorrect but Statement is correct
- BBoth Statement and Statement are correct
- CBoth Statement and Statement are incorrect
- DStatement is correct but Statement is incorrect
Correct answer
B. Both Statement and Statement are correct
Step-by-step solution
According to Bohr's postulates the angular momentum in stationary orbit is quantised and is equal to , where is the principal quantum number of the orbit. Bohr's model of the atom assumes fixed orbits and trajectories for the electron. Simultaneously known orbits and trajectories violate the Heisenberg Uncertainty Principle.
