Chromium: The Multi-Purpose Element
Chromium has many uses in today’s world. It is a versatile element which is found naturally in the earth’s crust, and is an important source of chromium metal used to make many everyday items such as stainless steel. It has many other uses too, from parts in cars to coloured glass.
It is a very important resource, making it an integral component of modern life.
History and Discovery of Chromium
The discovery of Chromium is credited to a French chemist, Louis Nicolas Vauquelin, who discovered it in 1797. Vauquelin was doing research on naturally occurring minerals, looking for new elements.
After painstaking analysis, he found that there was an element in rocks that gave them a beautiful green colour. This element was chromium – the multi-purpose element.
