(a) F is the most electronegative element,it means F is the only element which exhibits only negative oxidation state.
(b) Cs is the most electropositve element, it means Cs is the only element which exhibits only positive oxidation state.
(c) I exhibits both positive and negative oxidation state.Iodine exhibits -1, 0, +1,+3,+5,+7 [due to presence of vacant d orbitals positive oxidation state exhibits of iodine.
(d) Ne, Ar, Xe , Rn, He etc are inert gases, so, these are neither positive nor negative oxidation states.
