Question

Quizplus · Accepted Answer

A diamagnetic ion has all of its electrons paired, so it is not attracted to a magnetic field. Scandium (Sc) has only one unpaired electron in its 3d subshell, making it paramagnetic rather than diamagnetic. Copper (Cu), nickel (Ni), and chromium (Cr) all have unpaired electrons in their 3d subshells, making them paramagnetic as well. The only ion with all paired electrons is the  Sc3+ ion, making it the diamagnetic ion.
