Such a low standard atomic weight of aluminium has effects on the properties of the element. Īl is essentially the only isotope representing the element on Earth, which makes aluminium a mononuclidic element and practically equates its standard atomic weight to that of the isotope. No elements with odd atomic numbers have more than two stable isotopes even-numbered elements have multiple stable isotopes, with tin (element 50) having the highest number of stable isotopes of all elements, ten. 1995 - 2023.Main article: Radiation astronomy/Subatomics Periodic Table of Elements - Aluminum - Al.

England and elsewhere in the world they still spell it aluminium. American Chemical Society changed the spelling back to aluminum in 1925, which we still use. Two years later it was changed to aluminium to conform with the "ium" in most other elements. In 1807 Davy proposed the name alumium for this undiscovered metal, but it wasn't until 1827 that Wohler actually isolated aluminum, though an impure form was isolated by Oersted two years earlier. Lavoisier thought that alum was an oxide of this undiscovered metal. de Morveau recognized the base in alum in1761 and proposed it be called alumine. Actually the ancient Greeks and Romans used alum (aluminum sulfate with potassium) in medicine and in dying. ![]() Additional Notes: While aluminum was discovered by Hans Christian Oersted, Denmark, 1825 (impure form) most credit Wohler with isolating it in1827.Alloys containing copper, magnesium, silicon, manganese and other metals are much stronger and more durable than aluminum, making aluminum useful in the manufacture of aircraft and rockets. Uses of Aluminum: Kitchen utensils, building decorations, electrical transmission (not nearly as conductive as copper, but cheaper).Main mining areas are Surinam, Jamaica, Ghana, Indonesia and Russia. Total world production is around 15,000,000 tons per year. Obtained by electrolysis from bauxite (Al 2O2). Sources of Aluminum: Most plentiful metal in earth's crust (8%), but never occurs in free form.70kg human: 60 mg Who / Where / When / How Note: this data represents naturally occuring levels of elements in the typical human, it DOES NOT represent recommended daily allowances.
