Mercury (Mythology): Elements
built 653 days ago
Mercury Mercury is a Block D, Group 12, Period 6 element. The electronic configuration is [Xe] 4f14 5d10 6s2. In its elemental form mercury's CAS number is 7439-97-6. The mercury atom has a radius of 216.pm and it's Van der Waals radius is 155.pm.
[T]he word "Mercury" can refer to several different things, including: an element, a planet, an automobile brand, a record label, a NASA manned-spaceflight project, a plant, and a Roman god. Since only one Wikipedia page can have the generic name "Mercury", unambiguous article titles must be used for each of these topics: Mercury (element), Mercury (planet), Mercury (automobile), Mercury Records, Project Mercury, Mercury (plant), Mercury (mythology). There must then be a way to direct the reader to the correct specific article when an ambiguous term is referenced by linking, browsing or searching; this is what is known as disambiguation.
[T]o create a link to Mercury, just put double square brackets around the word — [[Mercury]] — producing Mercury. Now, Mercury is a disambiguation page, listing the several usages of the word. All Mercury links in an article probably refer to a particular Mercury, such as the element (Mercury (element)), the planet (Mercury (planet)), the automobile brand (Mercury (automobile)), the record label (Mercury Records), the NASA manned-spaceflight project (Project Mercury), the plant (Mercury (plant)), or the Roman god (Mercury (mythology)).
The abundance of mercury in the Earth's crust is estimated to be about 0.5 parts per million. That makes it one of the 20 least common elements. It very rarely occurs as an element. Instead, it is usually found as a compound. Its most common ore is cinnabar, or mercuric sulfide (HgS). Cinnabar usually occurs as a dark red powder.

Mercury has influenced the name of a number of things in a variety of scientific fields, such as the planet Mercury, the element mercury, and the plant mercury. The word [M]ercurial is commonly used to refer to something or someone erratic, volatile or unstable, derived from Mercury's swift flights from place to place.
