🔥❤️What are Halogens?

🟣Fluorine, Chlorine, Bromine and lodine are a group of elements known as halogens. They form a resemblance to each other and the compounds formed also have somewhat similar properties.

🔵Fluorine is the most reactive non-metal and reacts with most other elements. The gas is extremely toxic and dangerous because of its high reactivity with compounds that can be oxidized. It will react with water to produce great heat giving off toxic ad corrosive fumes.

🟢Chlorins is the commonest but most important of the halogens. The critical temperature is 144°C and it is easily liquefied under pressure at room temperature. Chlorine is an extremely toxic gas and was used as a poison gas in World War I. It reacts with water to form hydrochloric acid and hydrochloric acid. Chlorine is a highly reactive element and an oxidizing agent. It can react and even cause explosions with turpentine, ether, ammonia gas, hydrocarbons, hydrogen and powdered metals. The reaction with acetylene is very violent. Large quantities of chlorine are used in the bleaching of wood pulp, cotton and linen fabrics. It is also used in the manufacture of chlorine compounds such as carbon tetra chloride (CTC), hydrochloric acid, chlorates and insecticides.

🟡Bromine at room temperature is a dark red liquid, which readily releases toxic vapours. The liquid causes serious burns if it comes into contact with the skin. Bromine is an oxidizing agent and may ignite combustible substances with which it comes into contact

🟠Iodine is a dark-violet, almost black solid, which sublimes readily to give off a violet toxic vapour. To some extent it can react with oxidisable materials. It is almost insoluble in water but dissolves in alcohol to give tincture of iodine, which is sometimes used as an antiseptic
