REACTIVITY TOWARDS HALOGEN - TRIHALIDES

Explanation

Reactivity Towards Halogen - Trihalides

Halogens such as bromine, chlorine, and iodine have characteristics that empower them to respond with different elements to shape significant salts such as sodium chloride.

Characteristics of Halogens

Group 17 has elements like fluorine, chlorine, bromine, iodine, and astatine; it is also termed as the halogen group. At normal room temperature, fluorine is in the form of yellow gas, chlorine is a light green gas, bromine is a red fluid, and iodine is a purple solid. Astatine is a radioactive component and exists in nature just in tiny amounts. All the halogens exist as diatomic molecules. They have high ionisation energies and structure the most electronegative group of elements. Their electron design, ns2np5, allows them to react with Group 1 and 2 metals easily; every halogen tends to get one electron, and the Group 1 and Group 2 elements each will, in general, lose a couple of electrons, respectively. Halogens consequently react most vigorously with Group 1 and Group 2 metals of all primary group elements.
