Identify the liquid non metal among the following

Options

A. Mercury
B. Iodine
C. Bromine
D. None of these

Explanation

To identify the liquid non-metal among the given options, we can follow these steps:

### Step 1: Understand the Properties of Non-Metals
Non-metals are elements that typically lack the characteristics of metals. They can be found in various states (solid, liquid, gas) at room temperature.

### Step 2: Review the Given Options
We need to examine the options provided to determine which one is a liquid non-metal. The options mentioned in the video are:
1. Mercury (Hg)
2. Iodine (I2)
3. Bromine (Br)
4. A fourth option (not specified in the transcript)

### Step 3: Identify Each Element
- **Mercury (Hg)**: This is a metal that is liquid at room temperature.
- **Iodine (I2)**: This is a solid non-metal at room temperature.
- **Bromine (Br)**: This is a non-metal that is liquid at room temperature.
- **Fourth option**: Not specified, but we are focusing on the three mentioned.

### Step 4: Determine the Liquid Non-Metal
From the options analyzed:
- Mercury is a metal (liquid).
- Iodine is a solid non-metal.
- Bromine is a liquid non-metal.

### Conclusion
The liquid non-metal among the options provided is **Bromine (Br)**.

### Final Answer
**Bromine (Br)** is the liquid non-metal.
