Problem: Which of these ions has the smallest number of unpaired electrons?V2+Cr2+Ni2+Co2+Fe3+

FREE Expert Solution

To determine the number of unpaired electrons in an atom, let’s first write its electron configuration.

You can determine the ground-state electron configuration of electrons by referring to the periodic table and locating their position in the periodic table.

Ground-state means that the element is in its lowest energy form (not in excited state).
