which two elements are liquid at room temperature
Answer:
There are two elements that are liquid at room temperature, which are mercury and bromine.
Mercury is a transition metal with the atomic number 80 and symbol Hg. It is the only metal that is liquid at room temperature. Mercury is very dense, highly reflective, and has a low melting point. It has several uses in industry, such as in thermometers, barometers, and electrical switches.
Bromine, on the other hand, is a halogen element with the atomic number 35 and symbol Br. It is a red-brown liquid at room temperature and has a strong odor. Bromine is used in the manufacturing of flame retardants, dyes, and photographic chemicals.
It is important to note that both mercury and bromine can be toxic if not handled properly and should be used with caution.
