15) Which of the following, S, Xe, Hg, P are expected
to be diamagnetic in their ground state
configurations
Diamagnetic substance contain all paired electrons in their
atomic orbitals
Para magnetic substance has at least one unpaired electron in
their
atomic orbital
so let us see each elements electronic configuration
S = [Ne] 3s2 3p4
It has 4 electrons in the p subshell. Hence 2 of them are unpaired.
So it is
para magnetic
Xe= [Kr]4d10 5s2 5p6
This has completely filled orbitals .Hence all paired electrons in
the orbitals
So Xe is diamagnetic
Hg
[Xe] 4f14 5d10 6s2
All orbitals are completely filled .Hence the element is
diamagnetic
P
1s2 2s2 2p6 3s2 3p3
Unpaired electrons in p subshell. hence it is paramagnetic
