Mercury is an element that enters the environment through human activity and natural sources. It is a natural component of the Earth’s crust; however, the majority of mercury comes from improper disposal of mercury-containing products and the burning of fossil fuels. Natural emissions of mercury occur through the erosion of rocks, eruption of volcanoes and decomposition of soil.Know More
Although mercury is emitted into the atmosphere through both natural and man-made processes, only man-influenced or man-made mercury is deemed dangerous. Mercury is emitted into the air from vehicles and industrial spaces that burn fossil fuels. When emitted through these sources, mercury can travel hundreds of thousands of miles before dropping back to the Earth’s surface in the form of snow, rain and dry depositions. As a result, mercury infiltrates bodies of water and the fish we consume.
Mercury also enters the environment from the mishandling of mercury-containing products. Fluorescent lights, neon lamps, thermometers, thermostats, gauges and various laboratory solutions all contain traces of mercury. When these products are broken or improperly discarded, the mercury within them leaks out into the environment.
Mercury is known to have harmful effects on fish, birds and mammals. Due to its toxic nature, several states in the America have laws that regulate human activities involving mercury, including its removal and disposal.Learn more about Atoms & Molecules
No element has the chemical symbol "Nu." Other symbols that may be mistaken for "Nu" include: "Na," "Ne," and "N." "Na" stands for sodium, while "Ne" stands for neon, and "N" stands for nitrogen. Another possible element that could be misread as "Nu" is "Au," which stands for gold.Full Answer >
Francium has the lowest electronegativity of the elements listed on the Pauling Electronegativity Scale. The Angelo State University website defines electronegativity as an atom's ability to attract the shared electrons found in covalent bonds.Full Answer >
There is not much known about Mercury or its surface, except that it is similar to the moon in appearance and its composition consists of primarily molecular oxygen, sodium and hydrogen. There are also small amounts of helium and potassium. The planet does not have an actual atmosphere, which causes the planet to have extreme temperature changes during its rotation.Full Answer >
