Gold - Wikipedia

Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metalChemically, gold is a transition metal and a group 11 elementIt is one of the least reactive chemical elements and is solid under ....

Tungsten - Wikipedia

Tungsten, or wolfram, is a chemical element with symbol W and atomic number 74 The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tung sten or "heavy stone" Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone It was identified as a new element in 1781 and first ....

A very elongated form of the modern equality symbol (=) was introduced in print in The Whetstone of Witte (1557) by Robert Recorde (1510-1558) the man who first introduced algebra into England He justified the new symbol by stating that no two things can be more equal than a pair of ....

Structured Water Pseudoscience and Quackery - Chem1

Chemists have long recognized water as a substance having unusual and unique properties that one would not at first sight expect from a small molecule having the formula H 2 O It is generally agreed that the special properties of water stem from the tendency of its molecules to associate, forming short-lived and ever-changing polymeric units that are sometimes described as "clusters"...
