WebAug 12, 2016 · 2. First draw the electronic configuration for Iron. Now since we are given with Iron (II) we take out two electrons from the outermost orbit so as to give the iron a +2 charge. As evident from the configuration, in total there are 4 unpaired electrons. Using the same logic you can count the number of unpaired electrons for any ion.
