Uranium ores contain minute traces of polonium at levels of parts per billion. Some major uses of bromine have been discussed below: Bromine is a good oxidizing agent like other chlorine water and more useful as it does not decompose readily. Uses and properties John Emsley, Natures Building Blocks: An A-Z Guide to the Elements , Oxford University Press, New York, 2nd Edition, 2011. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. Radiocarbon dating measures radioactive isotopes in once-living organic material instead of rock, using the decay of carbon-14 to nitrogen-14. Uses and Occurrences: How the element is (or was) used or where it is found. Carbon dioxide (chemical formula CO 2) is a chemical compound occurring as a colorless gas with a density about 53% higher than that of dry air. CAS number Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old. The first is by the distillation of liquid air.

This difference in abundances can be observed in the Earths atmosphere, where the ratio of 4 He atoms to 3 He atoms is approximately 1000000:1. The second is to pass clean, dry air through a zeolite that absorbs nitrogen and leaves oxygen. Isotope vs. nuclide. Periodic Table. Isotopes of Sulfur.
