NEET Physics Hydrogen Atom Assertion Reason Question
Assertion (A): The ionisation energy of the hydrogen atom is the energy required to remove the electron from its lowest energy state.
Reason (R): According to Bohr's model, the ionisation energy is the energy required to transition the electron from n = 1 to n = ∞.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The ionisation energy of the hydrogen atom is defined as the energy required to remove its electron from the ground state (n = 1), which corresponds to the energy needed to excite the electron to n = ∞, as explained by Bohr's model.
