Vedclass · Answer

(A) 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 true: According to the Bohr model,the angular momentum of an electron in the ground state $(n=1)$ is $mvr = \frac{h}{2\pi}$.Statement $4$ is false: The radial probability distribution plots show that as $l$ increases,the electron density shifts further from the nucleus,but the statement regarding $\Psi$ vs $r$ is not a standard interpretation of orbital size trends.Therefore,the correct combination is $1$ and $3$.
