Statement (S): All s-orbital in

\mathrm{H}

-atom corresponds to a non-zero probability density at nucleus

Explanation (E): The probability density is given by:

\psi^2

and

\psi \propto e^{-\frac{Z r}{2 a_0}}

View answer and explanation

Correct option: C

Both S and E are correct and E is correct explanation of S

The correct answer is C (Both S and E are correct and E is correct explanation of S) because the probability density at the nucleus is non-zero for s-orbitals, and the given equation correctly describes the dependence of the wave function on the distance from the nucleus.
