Identify the metalloid among the following:

Options

A. Sodium
B. Silicon
C. Sulphur
D. Silver

Explanation

To identify the metalloid among the given options, 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 characteristics of both categories.

### Step 2: Analyze the options provided
We need to evaluate each option to determine if it is a metal, non-metal, or metalloid.

### Step 3: Evaluate each option
1. **Sodium (Na)**:
- Sodium is a metal.
- Atomic number: 11.
- Conclusion: This option is incorrect.

2. **Silicon (Si)**:
- Silicon is a metalloid.
- Atomic number: 14.
- Conclusion: This option is correct.

3. **Sulfur (S)**:
- Sulfur is a non-metal.
- Atomic number: 16.
- Conclusion: This option is incorrect.

4. **Silver (Ag)**:
- Silver is a metal.
- Atomic number: 47.
- Conclusion: This option is incorrect.

### Step 4: Identify the correct answer
After evaluating all the options, we find that the only metalloid among the given choices is **Silicon**.

### Final Answer:
The metalloid among the options is **Silicon**.
