Carbon generally forms four covalent bonds with other atoms in larger molecules.

Atomic number 6; atomic weight 12.011; sublimation point above 3,500°C; boiling point 4,827°C; specific gravity of amorphous carbon 1.8 to 2.1, of diamond 3.15 to 3.53, of graphite 1.9 to 2.3; valence 2, 3, 4.

The molybdenum isotopes allow us to clearly distinguish carbonaceous and non-carbonaceous material, and such from the outer and inner solar system," said Dr.

Gerrit Budde, paleontology in Münster University and the lead author of the study.

It can determine ages of items that are up to 60,000 years old. æ Because all living things contain Carbon and a small portion of that Carbon is the radioactive isotope Carbon14.

There would be little point in using other radio active isotopes which aren't naturally present in things which need to be dated. Carbon dating is the radio-activity of Carbon 14 which is unstable so it emits protons once in a while in order to become a more stable isotope.

Even though studies have showed that the carbonaceous meteorites are responsible for water on Earth though it still a mystery on how and when it happened."We have used molybdenum isotopes to answer this question.

A naturally abundant, nonmetallic element that occurs in all organic compounds and can be found in all known forms of life.

Diamonds and graphite are pure forms, and carbon is a major constituent of coal, petroleum, and natural gas.

Another example of radiometric dating is the dating of the age of geological formations on earth.

The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years. Carbon 14 has a half life of 5,730 years and by checking the amount of the carbon 14 is in a fossil the can see how old it is. Short Answer: Carbon 14 dating can only be used on objects which were once living things (plant or animal).Thus, establishing the syngeneity of the organic matter embedded in a mineral matrix is a crucial step in the study of very ancient rocks.
