What is hg element?

HG is the chemical symbol for the element mercury, which is a heavy, silvery-white metal. Mercury is a liquid at room temperature and has a high density, making it useful in various industrial applications, such as thermometers, barometers, and electrical switches. However, mercury is toxic and can cause serious health problems if ingested or inhaled. Therefore, its use is regulated and restricted in many countries. Mercury is also a major environmental pollutant, as it can enter the air and water systems from sources like coal-fired power plants and industrial processes. Measures are being taken globally to reduce the use and release of mercury to protect public health and the environment.
