Which of the following is semiconductor
Correct answer: D. Silicon
- A. Aluminium
- B. Diamond
- C. Graphite
- D. Silicon
Explanation
Silicon is the correct answer as it is a semiconductor with properties that allow it to be used in electronic devices. Semiconductors like silicon have conductivity levels between conductors and insulators, making them crucial for technology. Aluminium is a good conductor but not a semiconductor. Diamond is an insulator, lacking the conductivity needed for semiconductor functions. Graphite, although conductive, does not possess the specific semiconductor properties required for this question.

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.
