Which one of the following is a member of halogen family?

Options

A. Cu
B. Cr
C. Cl
D. Ca

Explanation

To determine which of the following elements is a member of the halogen family, we can follow these steps:

### Step 1: Understand the Halogen Family
The halogen family consists of elements that are found in Group 17 of the periodic table. The main members of this group include:
- Fluorine (F)
- Chlorine (Cl)
- Bromine (Br)
- Iodine (I)
- Astatine (At)
- Tennessine (Ts) (artificially created)

### Step 2: Identify the Elements Provided
In the question, we need to identify which of the provided elements belongs to the halogen family. Let's assume the options provided are:
- Cu (Copper)
- Cr (Chromium)
- Cl (Chlorine)
- Ca (Calcium)

### Step 3: Check Each Element Against the Halogen Family
- **Cu (Copper)**: This is a transition metal and does not belong to the halogen family.
- **Cr (Chromium)**: This is also a transition metal and is not a halogen.
- **Cl (Chlorine)**: This is a member of the halogen family.
- **Ca (Calcium)**: This is an alkaline earth metal and does not belong to the halogen family.

### Step 4: Conclusion
Among the given options, **Chlorine (Cl)** is the only element that belongs to the halogen family.

### Final Answer
Chlorine (Cl) is a member of the halogen family.
