Why is the element mercury important? The element mercury is important because it has a color of silver, it has the properties of a solid and a liquid, it is a naturally found element, and it doesn't break down.
Mercury metal has many uses. Because of its high density, it is used in barometers and manometers. Because it has a high rate of thermal expansion that is fairly constant over a wide temperature range, it is used extensively in thermometers.Mercury is important as a liquid contact material for electric switches.It is used in mercury-vapor lamps, which emit light rich in ultraviolet radiation; various kinds of such lamps are used for street lighting, as sun lamps, and in black lights (see lighting).ercury metal has many uses.
