Which of the following is true about Na, Si and S?
Correct answer: C. They are in the same period of the periodic table
- A. Their chlorides are ionic solids
- B. Covalent bond is found in most of the compounds
- C. They are in the same period of the periodic table
- D. They are in the same group of the periodic table
Explanation
The correct answer is Option C. Na, Si, and S all belong to the same period of the periodic table, which is the third period. This is a key characteristic shared by these elements. Options A and B are incorrect because not all of the elements mentioned exhibit the specific properties described in those options. Option D is incorrect as Na, Si, and S are not in the same group on the periodic table, rather they are in different groups.

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.
