Question

What is the only element in the halide family that is a liquid?

Answer 1

Hint: The elements which are present in VI A groups are called halogens. Halogens are the non-metallic elements and form acids when they are going to react with hydrogen. The physical state of all the halogens are not the same.

Complete answer:
- In the question it is asked to find the halide element which exists in liquid state.
- Fluorine, chlorine, bromine, iodine and astatine are called halogens and are present in the p-block.
- All the halogen atoms are non-metallic in nature.
- We know that fluorine and chlorine are gaseous in nature.
- Coming to Iodine and astatine they are solid in nature.
- Coming to the bromine atom, it is the only element among the halogens going to have liquid state.
- The boiling point of bromine is ${{59}^{o}}C$ .
- Means at ${{59}^{o}}C$ the bromine which is in liquid state starts converting into gaseous state.
- The drawback with liquid bromine is its corrosive nature and unbearable smell.
- Bromine is a red color liquid and exists in liquid form at room temperature.
- Therefore bromine is the only element among the halogens which is going to exist in liquid form.

Note:
Whenever we are going to use bromine in chemical reactions we are supposed to handle it carefully due to its nature of causing corrosion to the greatest extent and unbearable smell. Bromine is highly useful at the time of doing bromination reactions to reduce alkenes to haloalkanes.
