The more unpaired electrons an element contains, the more strongly paramagnetic it will be. (See Problem 6.57.) Among the elements in the third row of the periodic table, which one should be the most strongly paramagnetic?

Data from Problem 6.57

The magnetic properties of atoms provide evidence that Hund’s rule leads to the correct electron configuration. Atoms that contain one or more unpaired electrons display a weak form of magnetism and are said to be paramagnetic. Consider the elements in the second row of the periodic table and give the number of unpaired electrons found in each of them.
