The paramagnetic species is:
Correct answer: A. KO2
- A. KO2
- B. SiO2
- C. TiO2
- D. BaO2
Explanation
KO2 (potassium superoxide) is the correct answer as it contains an unpaired electron, making it paramagnetic and attracted to a magnetic field. The other options (SiO2, TiO2, BaO2) are diamagnetic and do not exhibit paramagnetic properties due to the absence of unpaired electrons in their molecular structures.

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.
