Vedclass · Answer

(C) Statement $1$ is true: Electrons in orbitals with higher angular momentum $(l)$ experience more shielding and are generally found further from the nucleus.Statement $2$ is false: The size of the orbital depends primarily on the principal quantum number $(n)$, not the azimuthal quantum number $(l)$.Statement $3$ is false: According to wave mechanics, the angular momentum of an electron is given by $\sqrt{l(l+1)} \frac{h}{2\pi}$. For the ground state of hydrogen $(1s)$, $l=0$, so the angular momentum is $0$, not $\frac{h}{2\pi}$.Statement $4$ is true: As the azimuthal quantum number $(l)$ increases, the radial wave function $\Psi(r)$ shows that the maximum probability density shifts to larger values of $r$.Therefore, the correct combination is $1$ and $4$.
