It can, however, be made by the same methods which have proved successful with manganese. What is Chromium? Preparation of ChromiumĬhromium, like manganese, is very hard to reduce from its ores, owing to its great affinity for Oxygen. The element also occurs in small quantities in many other minerals, especially in crocoisite (PbCrO4), in which mineral it was first discovered. The ore from which all chromium compounds are made is chromite, or chrome iron ore (FeCr2O4). What is Chromium? Occurrence of the Chromium Element He started his career working in an apothocary shop and then he became the laboratory assistant of Antoine-François Fourcroy before becoming an authority in his own right eventually chemistry professor at the Paris Faculty of Medicine. Nicolas-Louis Vauquelin rose from being born as the son of a peasant to an eminent chemist. Nicolas-Louis Vauquelin also discovered Beryllium. Elements classified as Transition Metals are generally described as ductile, malleable, and able to conduct electricity and heat.Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.įacts about the History and the Discovery of the Chromium ElementĬhromium was discovered by Louis Vauquelin in 1797 who was also able to detect traces of chromium in precious gems, such as ruby and emerald. Chromium is classified as a " Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. What is Chromium? Periodic Table Group and Classification of the Chromium ElementĮlements can be classified based on their physical states (States of Matter) e.g.
