Which oxides of "K" contain more oxygen than its normal oxide?
Correct answer: B. Super oxide
- A. Peroxide
- B. Super oxide
- C. Both contain equal quantity
- D. None of the above
Explanation
Potassium form normal oxide ( in which oxygen has oxidation state -2) K2O2. KO is peroxide (oxygen has oxidation state -1) has same no.of oxygen as normal oxide. KO2 is super oxide (oxygen has oxidation state -½) has more no. of oxygen than normal oxide.

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.
