Of the following which can be extracted by the electrolytic reduction of their salts?
Correct answer: B. Mg and Al
- A. Ag
- B. Mg and Al
- C. Ca
- D. All
Explanation
Magnesium and aluminium can be obtained by the electrolytic reduction of their ores respectively, as they are highly reactive metals with stable oxides that require electrolytic reduction. Silver (Ag) and Calcium (Ca) are not extracted by electrolytic reduction of their salts. Therefore, the correct answer is option B.

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.
