Which of the following oxides of an element is strongly basic in nature?
Correct answer: A. Na2O
- A. Na2O
- B. MgO
- C. Al2O3
- D. SO3
Explanation
Option A is correct because sodium oxide (Na2O) dissociates in water to form hydroxide ions, making the solution strongly basic. Option B (MgO) is basic but not strongly basic. Option C (Al2O3) is amphoteric, and Option D (SO3) is acidic. Therefore, the correct answer is sodium oxide (Na2O), as it exhibits strong basic properties.

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.
