HOW DOES Fe SHOW +6 O.S BUT NOT +5, SIMILARLY Co DOES NOT SHOW +5 O.S ?
dear Student,
Oxidation state is basically the number of electrons accepted or given by atom in order to get stable electronic configuration.
Fe electronic configuration :
so electronic configuration which has fully filled or half filled outermost shells are most stable. therefore Fe has 6 electrons in d orbital, so it either loses 1 electron and form half filled shell, or it looses all the six electons and attain stability.
similarly Co, it has the electronic configuration.
so it loses2 electrons or 7 electrons.
hope this concept is clear to you
