What is Carbon? Origin / Meaning of the name Carbon
The name originates from the Latin word 'carbo' meaning "charcoal". The French chemist, Antoine-Laurent de Lavoisier wrote a book outlining a method for naming chemical substances. The name he used for the element was carbone, based on the earlier Latin term for charcoal, carbo.
What is Carbon? Periodic Table Group and Classification of the Carbon Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Carbon is classified as an element in the 'non-metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metallic elements exist, at room temperature, in two of the three states of matter: gases (Oxygen, Hydrogen & Nitrogen) and solids (Carbon, Phosphorus, Sulfur and Selenium). For additional facts and information refer to Carbon Properties.
What is Carbon? Facts about the Discovery and History of the Carbon Element
Carbon was discovered and was known as soot and charcoal in Ancient times. French physicist René Antoine Ferchault Reaumur (1683-1757) investigated the differences between iron and steel, correctly showing that the amount of carbon is greatest in cast iron, less in steel, and least in wrought iron. His book on this subject and his belief that carbon might be an element was published in 1722.
In 1787, Antoine-Laurent de Lavoisier and three other French chemists wrote a book outlining a method for naming chemical substances. The name they used for the element was carbone, based on the earlier Latin term for charcoal, carbo.
What is Carbon? Occurrence of the Carbon Element
Carbon is found in nature in the uncombined state in several forms. The diamond is practically pure carbon, while graphite and coal are largely carbon, but contain small amounts of other substances. Its natural compounds are exceedingly numerous and occur as gases, liquids, and solids. Carbon dioxide is its most familiar gaseous compound. Natural gas and petroleum are largely compounds of carbon with Hydrogen. The carbonates, especially Calcium carbonate, constitute great strata of rocks, and are found in almost every locality. All living organisms, both plant and animal, contain a large percentage of this element, and the number of its compounds which go to make up all the vast variety of animate nature is almost limitless. Over one hundred thousand definite compounds containing carbon have been prepared. In the free state carbon occurs in three allotropic forms, two of which are crystalline and one amorphous.
