Question

Identify the metalloid element from the following.

• A. \(\text{O}\)
• B. \(\text{S}\)
• C. \(\text{Te}\)
• D. \(\text{Cl}\)

Hint:

Metalloids lie along the zig-zag line between metals and non-metals in the p-block.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Metalloids show properties between metals and non-metals. The common ones are B, Si, Ge, As, Sb and Te.

Step 2: Compare the options
\(\text{O}\) and \(\text{S}\) are non-metals of group 16 and \(\text{Cl}\) is a non-metallic halogen.

Step 3: Conclusion
\(\text{Te}\), lower in group 16, shows semiconducting and partly metallic behaviour, so it is the metalloid.

Final Answer:
Tellurium is the metalloid. \[ \boxed{\text{(C) }\text{Te}} \]
