For determining the no. of unpaired electrons, you must know about the electronic configuration of the elements of the periodic table. Then theorbital which comes at the last in the configuration is to be observed. It may be - s,p,d or f . The ‘s’ orbital contains max of 2 electrons whereas max electrons in p,dand f are 6,10 and 14. If the last orbital contains electrons less than the maximum number of electrons that should be present in an orbital then thedifference of the maximum number of electrons which can be present in the subshell are subtracted with the electrons present in the last subshell ofthe electronic configuration.
For example- the electronic configuration of any element is “1s^2, 2s^2, 2p^5”
in this case 2p^5 is the lastorbital of the electronic configuration then in this case the number of unpaired electrons are ‘1’
as p orbital contains maximum of 6 electrons and there are 5 electrons present in the orbital so the unpaired electrons are given by(6–5)=1903Views·
