Why are halogens coloured?
Explanation Halogens are the member of group 18. They have a very small atomic radii and more number of protons in nucleus due to this they have very high nuclear charge. When halogens are in visible light their molecules absorbs light. With the energy of this light their electrons gets excited to the higher energy level and remaining light is transmitted. These transmitted lights produce the color of the halogens. Final Answer Halogens are colored due to absorption and transmission of light.
