The operating temperature of Down's cell is:
Correct answer: B. 600oC
- A. 800oC
- B. 600oC
- C. 1800oC
- D. 900oC
Explanation
This is the correct operating temperature of a Down's cell. The temperature is kept around 600°C to ensure that the electrolyte (a mixture of sodium chloride and calcium chloride) remains molten, allowing for the electrolytic production of sodium metal.

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.
