Phosphorous shows oxidation state (+3) in which of the following:
Correct answer: C. H3PO3
- A. H4P2O7
- B. PO4-3
- C. H3PO3
- D. H3PO4
Explanation
It can have a +3 oxidation state when it shares its three electrons with the atoms more electronegative than it. Phosphorus has oxidation state in Phosphorus acid ( H 3 PO 3 ) also in Phosphorous trichloride .

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
