NEET Physics (general) Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 12

Assertion (A): The Bohr model of the hydrogen atom predicts the ionisation energy accurately. | Reason (R): In the Bohr model, the energy of an atom is least when the electron is in the orbit with the Bohr radius.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

The Bohr model accurately predicts the hydrogen atom's ionisation energy, as it is based on the electron being in the orbit with the Bohr radius having the least energy. This matches the NCERT context which states the energy is least when the electron is in the smallest orbit.
