Liquid oxygen sticks to the magnet pole but liquid nitrogen doesnt. why?

Expert Answer:

Liquid oxygen sticks to a magnet while liquid nitrogen does not because of differences in electron distribution.

One possible Lewis structure for O2 shows an unpaired electron on each oxygen atom.

Molecules with unpaired electrons are called paramagnetic and exhibit magnetic properties.

                         

The Lewis structure of N2 does not have unpaired electrons. Molecules with no unpaired electrons that do not exhibit magnetic properties are called diamagnetic.
