Read the Assertion and Reason below and choose the correct option. — Atomic Structure Chemistry Question

💡 Solution & Explanation

The orbital angular momentum is given by the formula $\sqrt{l(l+1)}\frac{h}{2\pi}$. For an s-orbital, the azimuthal quantum number $l=0$. Substituting $l=0$ into the formula yields zero angular momentum. Statement I is true, Statement II is true, and Statement II is the correct explanation for Statement I. Therefore, correct answer is A.
