Chemistry · Structure of atom

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The energy of an electron in a hydrogen atom has a negative sign for all possible orbits. Reason (R): This negative sign means that the energy of the electron in the atom is lower than the energy of a free electron at rest. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
