Question

Assertion: 3s, 3p and 3d subshells of hydrogen have the same energy.
Reason: Energy of subshells in the hydrogen atom, depends on the principal quantum number (n) and azimuthal quantum number (l).

• A. Both Reason and Assertion are true and reason is the. correct explanation of assertion
• B. Both Reason and Assertion are true but reason is not correct explanation of assertion
• C. Assertion is true but reason is false
• D. Assertion and reason both are false
• E. Assertion is false but reason is true

Answer 1

The correct option is C Assertion is true but reason is false

3s,3p and 3d have subshells have same energy because they are degenerate orbitals in a Hydrogen atom.

In Hydrogen atom energy depends on only Principle quantum number (as It has only one electron )
