Assertion: In n=2, energy of electron in hydrogen like atoms is more compared to n=1
.Reason: Electrostatic potential energy in n=2 is more.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason or true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`(E_2 = -3.4 eV, U_2 = -6.8 eV)}`
`(E_1 = -13.6 eV , U_1 = -27.2 eV)}`
`E_2 gt E_1, similarly U_2 gt U_1`
