“Which element is liquid at room temperature?”

"Bromine is one of two elements (alongside mercury) that is liquid at room temperature. A halogen it is reddish-brown volatile and used in flame retardants disinfectants and chemical synthesis. Its unique physical state makes it significant in chemistry particularly for studying phase transitions and molecular properties. Handling bromine requires caution due to its toxicity and corrosiveness. Its applications in industry and research underscore the importance of understanding elemental properties contributing to advancements in materials science and chemical engineering for practical and industrial purposes."
