Pure carbon forms diamond by bonding to four other carbon atoms in a three dimensional crystal. The name carbon-14 tells us that this isotope's mass number is #14#. Although the existence of hydrocarbons on extraterrestrial bodies like Saturn's moon Titan indicates that hydrocarbons are sometimes naturally produced by inorganic means, abiogenic petroleum origin is a largely discredited hypothesis which proposes that most of earth's petroleum and natural gas deposits were also formed inorganically. Drop all the files you want your writer to use in processing your order. The best way to upload files is by using the additional materials box. The ratio of normal carbon (carbon-12) to carbon-14 in the air and in all living things at any given time is nearly constant.
