CAS 7439-97-6

:

Mercury

Description:
Mercury, with the CAS number 7439-97-6, is a heavy metal and the only metal that is liquid at room temperature. It has a silvery-white appearance and is known for its high density and ability to form amalgams with other metals. Mercury is a poor conductor of heat but a good conductor of electricity. It has a relatively low melting point and boiling point compared to other metals, which contributes to its liquid state at ambient temperatures. Mercury is highly toxic, particularly in its organic forms, such as methylmercury, which can bioaccumulate in living organisms and pose significant health risks. It is used in various applications, including thermometers, barometers, and some types of electrical switches, although its use has declined due to environmental and health concerns. Mercury exists in several oxidation states, with elemental mercury (Hg^0), mercurous (Hg2^2+), and mercuric (Hg^2+) being the most common. Its unique properties and toxicity necessitate careful handling and regulation in industrial and laboratory settings.
