And carbon dating

This black soot, also known as lampblack, gas black, channel black or carbon black, is used to make inks, paints and rubber products.

It can also be pressed into shapes and is used to form the cores of most dry cell batteries, among other things.

While scientists sometimes conceptualize electrons spinning around an atom's nucleus in a defined shell, they actually fly around the nucleus at various distances; this view of the carbon atom can be seen here in two electron cloud figures (bottom), showing the electrons in a single blob (the so-called s-orbital) and in a two-lobed blob or cloud (the p-orbital). It can link to itself, forming long, resilient chains called polymers.

It can also bond with up to four other atoms because of its electron arrangement.

Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.

Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.

Nearby, workers also uncovered an assortment of thick and heavily fossilized bones. Arrange carbon atoms in one way, and they become soft, pliable graphite. — the atoms form diamond, one of the hardest materials in the world.Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and the basis for technological marvels such as graphene, which is a material stronger than steel and more flexible than rubber. History and Uses: Carbon, the sixth most abundant element in the universe, has been known since ancient times.Amorphous carbon is formed when a material containing carbon is burned without enough oxygen for it to burn completely.
