Liquid non-metal among the following

Options

A. Br
B. Te
C. Hg
D. I

Explanation

To determine the liquid non-metal among the given options, we can analyze each option based on their physical states at room temperature.

### Step 1: Identify the options
The options provided are:
- A) Bromine
- B) Tellurium
- C) Mercury
- D) Iodine

### Step 2: Analyze each option
1. **Bromine (Br)**: Bromine is a non-metal and is known to be a liquid at room temperature (approximately 20°C). It is the only non-metal that is liquid under these conditions.

2. **Tellurium (Te)**: Tellurium is a metalloid and is solid at room temperature.

3. **Mercury (Hg)**: Mercury is a metal and is also liquid at room temperature. However, it does not qualify as a non-metal.

4. **Iodine (I)**: Iodine is a non-metal, but it is solid at room temperature.

### Step 3: Conclusion
From the analysis, the only liquid non-metal among the options is **Bromine (A)**.

### Final Answer
The liquid non-metal among the following options is **Bromine (A)**.
