Joel has just started his first day working as a scientist in a laboratory. The first task he was given is to look at two atoms and to jot down as much information about the two as he can. First, he needs to come up with an identification for these atoms. Since he is new, he decides to keep it professional and simply call the larger of the two atoms "atom L" and the smaller one "atom S". Now that he's taken care of that he can get down to work. Is the shielding effect in atom S higher or lower than in atom L?
