  2. Aluminium amalgam - Wikipedia

    en.wikipedia.org/wiki/Aluminium_amalgam

    Al(Hg) may be prepared by either grinding aluminium pellets or wire in mercury, or by allowing aluminium wire to react with a solution of mercury(II) chloride in water. [2] [3] [1] This amalgam is used as a chemical reagent to reduce compounds, such as of imines to amines. The aluminium is the ultimate electron donor, and the mercury serves to ...

  3. Amalgam (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Amalgam_(chemistry)

    Aluminium can form an amalgam through a reaction with mercury. Aluminium amalgam may be prepared by either grinding aluminium pellets or wire in mercury, or by allowing aluminium wire or foil to react with a solution of mercuric chloride. This amalgam is used as a reagent to reduce compounds, such as the reduction of imines to amines.

  4. Mercury (element) - Wikipedia

    en.wikipedia.org/wiki/Mercury_(element)

    Mercury readily combines with aluminium to form a mercury-aluminium amalgam when the two pure metals come into contact. [25] Since the amalgam destroys the aluminium oxide layer which protects metallic aluminium from oxidizing in-depth (as in iron rusting), even small amounts of mercury can seriously corrode aluminium. For this reason, mercury ...

  5. Group 12 element - Wikipedia

    en.wikipedia.org/wiki/Group_12_element

    2, two mercury(I) ions come together to form a metal-metal bond and a diamagnetic species. [24] Cadmium can also form species such as [Cd 2 Cl 6 ] 4− in which the metal's oxidation state is +1. Just as with mercury, the formation of a metal-metal bond results in a diamagnetic compound in which there are no unpaired electrons; thus, making the ...

  6. Dental amalgam controversy - Wikipedia

    en.wikipedia.org/wiki/Dental_amalgam_controversy

    In 1818, Parisian physician Louis Nicolas Regnart added one-tenth by weight of mercury to the fusable metals used as fillings at the time to create a temporarily soft metal alloy at room temperature. Thus, amalgam (an alloy of mercury with another metal or metals, from the French word amalgame) was invented.

  8. Amalgam (dentistry) - Wikipedia

    en.wikipedia.org/wiki/Amalgam_(dentistry)

    Amalgam filling on first molar. In dentistry, amalgam is an alloy of mercury used to fill teeth cavities. [1] It is made by mixing a combination of liquid mercury and particles of solid metals such as silver, copper or tin.

  9. Alchemical symbol - Wikipedia

    en.wikipedia.org/wiki/Alchemical_symbol

    The tradition remains today with the name of the element mercury, where chemists decided the planetary name was preferable to common names like "quicksilver", and in a few archaic terms such as lunar caustic (silver nitrate) and saturnism (lead poisoning). [4] [5] Lead, corresponding with Saturn ♄ Tin, corresponding with Jupiter ♃ ()
