Potassium argon dating false

Some alchemists called this zinc oxide lana philosophica, Latin for "philosopher's wool", because it collected in wooly tufts, whereas others thought it looked like white snow and named it nix album.The name of the metal was probably first documented by Paracelsus, a Swiss-born German alchemist, who referred to the metal as "zincum" or "zinken" in his book Liber Mineralium II, in the 16th century.Other applications are in electrical batteries, small non-structural castings, and alloys such as brass.A variety of zinc compounds are commonly used, such as zinc carbonate and zinc gluconate (as dietary supplements), zinc chloride (in deodorants), zinc pyrithione (anti-dandruff shampoos), zinc sulfide (in luminescent paints), and zinc methyl or zinc diethyl in the organic laboratory.The element was probably named by the alchemist Paracelsus after the German word Zinke (prong, tooth).

Zinc tends to form bonds with a greater degree of covalency and much more stable complexes with N- and S- donors.Soil contains zinc in 5–770 ppm with an average 64 ppm.Seawater has only 30 ppb and the atmosphere, 0.1–4 µg/m Zinc is a chalcophile, meaning the element is more likely to be found in minerals together with sulfur and other heavy chalcogens, rather than with the light chalcogen oxygen or with non-chalcogen electronegative elements such as the halogens.This may refer to small quantities of zinc that is a by-product of smelting sulfide ores.Alchemists burned zinc metal in air and collected the resulting zinc oxide on a condenser.

Radiocarbon dating is used to measure the age of fossils true or false. Potassium-argon dating has been used to date volcanic layers above and below.
