History and Uses: Carbon, the sixth most abundant element in the universe, has been known since ancient times.

The product of this reaction can be predicted, once again, by assuming that mass and charge are conserved. They rapidly lose their kinetic energy as they pass through matter.

As soon as they come to rest, they combine with an electron to form two -ray photons in a matter-antimatter annihilation reaction.-decay are often obtained in an excited state.

Naturally occurring graphite occurs in two forms, alpha and beta.

These two forms have identical physical properties but different crystal structures.

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.

Alpha decay is usually restricted to the heavier elements in the periodic table.

(Only a handful of nuclides with atomic numbers less than 83 emit an -particle.) The product of -decay is easy to predict if we assume that both mass and charge are conserved in nuclear reactions.

Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.

There are over forty such techniques, each using a different radioactive element or a different way of measuring them.

Wiens has a Ph D in Physics, with a minor in Geology.
