The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Group of Elements**: - Halogens belong to Group 17 of the periodic table. The elements in this group are fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). 2. **Determine the Physical States of Halogens**: - Fluorine (F) is a gas at room temperature. - Chlorine (Cl) is also a gas at room temperature. - Bromine (Br) is a liquid at room temperature. - Iodine (I) is a solid at room temperature. 3. **Identify Liquid and Solid Halogens**: - From the above information, we can conclude that: - The liquid halogen is bromine (Br). - The solid halogen is iodine (I). 4. **Final Answer**: - Therefore, the liquid and solid halogens are bromine (Br) and iodine (I), respectively.
