Which of the following is metalloid?

Options

A. Sb
B. Mg
C. Zn
D. Bi

Answer

To determine which of the given elements is a metalloid, we can follow these steps:

### Step 1: Understand the Definition of Metalloids
Metalloids are elements that have properties intermediate between metals and non-metals. They typically exhibit a mix of metallic and non-metallic characteristics.

### Step 2: Identify the Given Elements
The elements provided in the question are:
- Sb (Antimony)
- Mg (Magnesium)
- Zn (Zinc)
- Bi (Bismuth)

### Step 3: Locate the Elements on the Periodic Table
To identify which of these elements is a metalloid, we can refer to the periodic table. The metalloids are typically found along the zig-zag line that separates metals from non-metals.

### Step 4: Analyze Each Element
- **Sb (Antimony)**: Located in group 15, it is classified as a metalloid.
- **Mg (Magnesium)**: Located in group 2, it is classified as a metal.
- **Zn (Zinc)**: Located in group 12, it is classified as a metal.
- **Bi (Bismuth)**: Located in group 15, it is classified as a metal.

### Step 5: Conclusion
Based on the classification, the only metalloid among the options provided is **Sb (Antimony)**.

### Final Answer
The answer is **Sb (Antimony)**.
