why is alkali metal paramagnetic in nature and their salts not show this reason

Asked by 9th January 2012, 8:20 PM
Answered by Expert


All the alkali metals are paramagnetic because of the presence of one valence electron in the valence shell. The alkali metal cations i.e. Li+, Na+, K+, Rb+ and Cs+ all are diamagnetic because of absence of unpaired electrons. Therefore, their salts do not show paramagnetic property.
