What are the physical properties of mercury?

Physical Properties. Mercury is a silvery-white, shiny metal, which is liquid at room temperature. Due to its high surface tension, mercury has the ability to wet metals. When the solubility limit of a metal in mercury is exceeded, mercury still can wet the metal forming a thick silvery amalgam paste.

What is the physical property of mercury?

Mercury has a melting point of -38.9^oC, a boiling point of 356.7^oC, and is the only metal to remain in liquid form at room temperature. Droplets of liquid mercury are shiny and silver-white with a high surface tension, appearing rounded when on flat surfaces.

Is mercury physical or chemical?

Mercury is a chemical element with the symbol Hg and atomic number 80.

Is mercury liquid or solid?

Mercury is both a liquid at room temperature (as it has a very low melting point of -39C) and a metal. We tend to assume metals are all solids but they are not.

What are the properties and uses of mercury?

Although many liquids could be used in pressure measuring devices, mercury is used because its high density requires less space. It is also a good conductor of electricity, so it is a useful component of electrical switches. Mercury is also used in dental fillings, paints, soaps, batteries, and fluorescent lighting.

What texture is mercury?

Mercury is the only elemental metal that is liquid at room temperature. (Cesium melts at about 28.5 °C [83 °F], gallium at about 30 °C [86 °F], and rubidium at about 39 °C [102 °F].) Mercury is silvery white, slowly tarnishes in moist air, and freezes into a soft solid like tin or lead at −38.83 °C (−37.89 °F).

What are two physical properties of mercury that make it useful for gold mining?

Just as water is an effective solvent of many substances because of its chemical composition, mercury's atomic structure makes it an effective solvent of most metals. This, combined with its low boiling point, make it useful for extracting gold from ore in a process of amalgamation and distillation.

Which properties best describes the element mercury?

Mercury is the only common metal which is liquid at ordinary temperatures. Mercury is sometimes called quicksilver. It is a heavy, silvery-white liquid metal. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity.

What is mercury physical state at room temperature?

Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature.

Does mercury solidify?

According to modern chemistry, you cannot solidify mercury at room temperature; you can solidify mercury only if you take it to -38 degrees Centigrade. ... But now at room temperature, mercury is solidified without any addition.

Is mercury magnetic?

It is the only rocky planet that has a global magnetic field like Earth. ... Measurements made by Mariner 10 in 1974/75 showed that Mercury also has a magnetic field. According to the standard models, the dynamo effect in its metal core should generate similar field strengths to those on Earth.

Is mercury poisonous to touch?

Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.

What is in the Mercury?

Mercury appears to have a solid silicate crust and mantle overlying a solid, iron sulfide outer core layer, a deeper liquid core layer, and a solid inner core. The planet's density is the second highest in the Solar System at 5.427 g/cm³, only slightly less than Earth's density of 5.515 g/cm³.

Why mercury is used in thermometer?

Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
