🤓 Based on our data, we think this question is relevant for Professor Youssef's class at TOWSON.
An electron in a(n) __________ subshell experiences the greatest effective nuclear charge in a many-electron atom.
We’re being asked to determine the orbital that experiences the most shielding.
Recall that shielding is the resistance of an electron from the attractive forces exerted by the nucleus.
Electrons that are further away from the nucleus have greater shielding. This means the orbital that experiences that greatest shielding is farthest from the nucleus.
