What is the colour and physical state of bromine?

Bromine is characterized as a dense, poisonous red-brown volatile liquid at room temperature. This unique state sets bromine apart from many other elements in the halogen group, such as chlorine, which is a gas, and iodine, which is a solid. The red-brown color of bromine is due to its molecular structure and its absorption of certain wavelengths of light. Additionally, its volatility indicates that it can readily evaporate into a gas, particularly when heated, which is a significant property for various applications in chemical processes. The combination of its color, density, and physical state as a liquid makes bromine distinct in the periodic table and essential to understand in context with its properties and potential uses.
