Actinium is a soft, silvery-white, [17] [18] radioactive, metallic element. Its estimated shear modulus is similar to that of lead . [ 19 ] Owing to its strong radioactivity, actinium glows in the dark with a pale blue light, which originates from the surrounding air ionized by the emitted energetic particles. [ 20 ]
The term is also used in the antiques trade for an item suspected of being silver, but not hallmarked. A white metal alloy may include antimony, tin, lead, cadmium, bismuth, and zinc (some of which are quite toxic). Not all of these metals are found in all white metal alloys. Metals are mixed to achieve a desired goal or need.
AA-8000: used for electrical building wire in the U.S. per the National Electrical Code, replacing AA-1350. [1]Al–Li (2.45% lithium): aerospace applications, including the Space Shuttle
Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals.
Silver is a chemical element; it has symbol Ag (from Latin argentum 'silver', derived from Proto-Indo-European *h₂erǵ ' shiny, white ') and atomic number 47. A soft, white, lustrous transition metal , it exhibits the highest electrical conductivity , thermal conductivity , and reflectivity of any metal . [ 11 ]
Silver is a metallic chemical element with the chemical symbol Ag (Latin: argentum, from the Indo-European root *arg-for "grey" or "shining") and atomic number 47. A soft, white, lustrous transition metal , it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Rhodium is a chemical element; it has symbol Rh and atomic number 45. It is a very rare, silvery-white, hard, corrosion-resistant transition metal. It is a noble metal and a member of the platinum group. It has only one naturally occurring isotope, which is 103 Rh.
