Question

Consider the 4p electrons and use your molecular theory to determine if Br2 would be paramagnetic or dimagnetic?? Ok was is really meant by para and di magnetic and how to determine if an atom is para or di????

Answer 1

Bascially, with molecular theory, unpaired electrons are attracted to a magnetic field (paramagnetic) and paired electrons are repelled by a magnetic field (diamagnetic). Using a molecular orbital diagram (look it up if you dont know what im talking about) and putting all the bonding electrons in it, we see that all electrons are paired and therefore Br2 is diamagnetic.
