Tin Chemical Symbol

In ancient Babylon these symbols were given for the metals gold, copper, tin, iron, silver, mercury and lead. They are still widely used today in chemical charts.

Tin is a chemical element with symbol Sn (for Latin: stannum) and atomic number 50. It is a main group metal in group 14 of the periodic table. Tin shows chemical similarity to both neighboring group-14 elements, germanium and lead, and has two possible oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table.

Thallium is a chemical element with symbol Tl and atomic number 81. This soft gray post-transition metal is not found free in nature. When isolated, it resembles tin, but discolors when exposed to air. Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly developed method of flame spectroscopy, in which thallium produces a notable green spectral line.

Indium is a chemical element with symbol In and atomic number 49. It is a post-transition metal that makes up 0.21 parts per million of the Earth's crust. Very soft and malleable, Indium has a melting point higher than sodium and gallium, but lower than lithium or tin. Ferdinand Reich and Hieronymous Theodor Richter discovered it with spectroscopy in 1863, naming it for the indigo blue line in its spectrum. It was isolated the next year.

Indium is a chemical element with symbol In and atomic number 49. It is a post-transition metallic element that is rare in Earth's crust. It has no obvious role in biological processes, but is of considerable industrial importance. The metal is very soft, malleable and easily fusible, with a melting point higher than sodium, but lower than lithium or tin.

Tin is a chemical element with the symbol Sn.Tin has many uses. It takes a high polish and is used to coat other metals to prevent corrosion, such as in tin cans, which are made of tin-coated steel. Alloys of tin are important, such as soft solder, pewter, bronze and phosphor bronze. A niobium-tin alloy is used for superconducting magnets.

alchemy symbol: Mercury | Alchemists were convinced that mercury transcended both the solid and liquid states, both earth and heaven, both life and death. Mercury is one of the seven metals of alchemy (gold, silver, mercury, copper, lead, iron & tin). The symbol for mercury could also be used to represent the planet of the same name in astrology. The metal is often also represented by a serpent or snake.
