🤓 Based on our data, we think this question is relevant for Professor Randles' class at UCF.
We’re being asked to determine the orbital in which an electron in a lithium (Li) atom 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.
In which orbital does an electron in a lithium atom experience the greatest shielding?
