Mercury occurs naturally in the environment and exists in many forms. In pure form, it is known as "elemental" or "metallic" mercury. Elemental mercury is a shiny, silver-white metal that is liquid at room temperature. It is not found in this form in nature, but in compounds and inorganic salts.
This is a list of prices of chemical elements.Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.
The amount of mercury in a fluorescent lamp varies from 3 to 46 mg, depending on lamp size and age. [4] Newer lamps contain less mercury and the 3–4 mg versions are sold as low-mercury types. A typical 2006-era 4 ft (122 cm) T-12 fluorescent lamp (i.e. F34T12) contains about 5 milligrams of mercury. [5]

Mercury cannot be used below the temperature at which it becomes solid, −38.83 °C (−37.89 °F). If the thermometer contains nitrogen, the gas may flow down into the column when the mercury solidifies and be trapped there when the temperature rises, making the thermometer unusable until returned to the factory for reconditioning.
