Question

Assertion and Reason Type :
Assertion (A): The transition of electrons n3 →n2, in H-atom will emit greater energy than n4 to n3
Reason (R): n3 and n2 are closer to the nucleus than n4
a) Both (A) and (R) are true and (R) is the correct explanation of (A)
b) Both (A) and (R) are true and (R) is not the correct explanation of (A)
c) (A) is true but (R) is false
d) (A) is false but (R) is true​

Answer 1

Answer:

B

Explanation:

Both assertion and reason are true but reason is not the correct explanation of assertion. The difference between the energies of adjacent energy levels decreases as we move away from the nucleus. Thus in H atom

`E_2-E_1 gt E_3 -E_2 gt E_4 -E_3`....
