Which one is a non-metál which conducts electricity ?

Options

A. Copper
B. Bromine
C. Graphite
D. Mercury

Explanation

To solve the question "Which one is a non-metal which conducts electricity?", we can follow these steps:

### Step 1: Identify the Options
First, we need to look at the options provided in the question. The options typically include a mix of metals and non-metals.

### Step 2: Eliminate Metals
Next, we identify and eliminate the metals from the options:
- Copper is a metal.
- Mercury is also a metal.

By eliminating these two, we narrow down our choices to non-metals.

### Step 3: Evaluate Non-Metals
Now, we need to evaluate the remaining non-metal options:
- Bromine is a non-metal, but it does not conduct electricity.
- Graphite is an allotrope of carbon, which is a non-metal.

### Step 4: Determine Conductivity
Now, we need to check which of the remaining non-metals can conduct electricity:
- Graphite has a unique structure with hexagonal packing, allowing it to have free or mobile electrons. This structure enables it to conduct electricity.

### Step 5: Conclusion
Based on the evaluation, the non-metal that conducts electricity is graphite.

### Final Answer
The non-metal which conducts electricity is **Graphite**.
