Solution: Consider the elements: Na, Mg, Al, Si, P.Which element is diamagnetic?

Solution: Consider the elements: Na, Mg, Al, Si, P.Which element is diamagnetic?

Problem

Consider the elements: Na, Mg, Al, Si, P.

Which element is diamagnetic?

Solution

Recall that a diamagnetic element does not have an unpaired electron; this means that, all electrons in its orbitals are paired up.  Elements that belong under Groups: 2A, 8A, and the transition metal group (beside Carbon/Group 3A) with completely filled orbitals (electron configuration ending in s2, p6, d10) are diamagnetic.
