Mercury – Hydrargyrum (Hg) Mercury's original Latin name was actually 'argentum vivum' (living silver), but Latin later borrowed from the Greek 'hydrargyros' (liquid silver) to give 'hydrargyrum'. The original English name for the element was 'quicksilver'.
Chemical Elements Quiz. Name the correct symbol for as many of the first 110 chemical elements in the periodic table as you can. All chemical matter found on earth comes from these elements. Each has a distinct atom featuring an atomic number (the number of protons in its nucleus) and electrons.
Aug 13, 2017· When mercury is added to aluminum, it forms an amalgam (a mercury alloy). Aluminum is normally protected by a thick oxide layer, but the formation of the amalgam disrupts it.
Mercury (meaning Mind): is one of the three heavenly substances as well as the seven metals of alchemy. To alchemists, the mercury alchemical symbol rises above both the liquid and solid states, both heaven and earth, and even death and life. Mercury is used to symbolize the planet "Mercury" in astrology.
MERCURIC NITRATE is noncombustible, but, as an oxidizing agent, will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Light sensitive. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates.
Mercury Chemical Symbol Hg, also known as quicksilver. Hg (hydrargyrum) is derived from the Greek word hydrargyros, which is a compound word meaning 'water' and 'silver' — since it is liquid like water, and yet has a silvery metallic sheen.
Can you name the element by symbol? Plays Quiz Updated Aug 14, 2018
A scientific symbol can be anything from a picture you see that tells you about an object or an area, such as whether something is corrosive or extremely hot, to the abbreviation of an element in the periodic table. Symbols can be methods of measuring things like energy (joules) and heat (degrees Celsius) or letters of the Greek alphabet that ...
Dec 01, 2013· The number of neutrons is the mass number minus the atomic number. Mercury (chemical symbol Hg) has chemical number 80 on the periodic table which means 80 protons and 80 electrons. The number of neutrons can vary but would normally be the same at the number of protons 80 but may be more or less.

A short film about the chemistry of Mercury, presented by The Periodic Table of Videos.
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Finding molar mass starts with .
Mercury has an atomic weight of amu, and its chemical symbol is Hg. Protons are particles that carry a positive charge. They exist in the nucleus of an atom along with neutrons, which have no charge. In addition to 80 protons, mercury has 80 electrons and 121 neutrons in its stable state.
Jul 08, 2016· Explanation: The mercurous ion is Hg2+ 2. Clearly the oxidation state of each mercury centre is +I. I have never used this mercurous nitrate reagent, but given that we combine a subvalent metal, and a potent oxidizing agent in the nitrate ion, I don't think it would be too stable.
Like a few other elements, mercury has a chemical symbol, Hg, that bears no resemblance to its name. This is because Hg is an abbreviation of the Latin name of the element, which was hydrargium. This word in turn was taken over from Greek, where it literally meant watersilver.
Mercury is a metal that is a liquid at room temperature. Mercury has a long and interesting history deriving from its use in medicine and industry, with the resultant toxicity produced. In high enough doses, all forms of mercury can produce toxicity. The most devastating tragedies related to mercury toxicity in recent history include Minamata Bay and Niagata, Japan in the 1950s, and Iraq in ...
