Which electron,$2s$ or $2p$,is more strongly attracted to the nucleus? Explain.
(A) The $2s$ electrons are more strongly attracted to the nucleus than the $2p$ electrons. This is because the $2s$ orbital is closer to the nucleus and has a higher probability density near the nucleus compared to the $2p$ orbital,which experiences greater shielding from the inner shell electrons.
