7th Period, Group 12
Discovery
Copernicium was discovered February 9, 1996
Discovery
- Discovered by team led by Sigfurd Hofmann
- Created the element by bombarding lead-208 nuclei with zinc-70 nuclei in a heavy ion accelerator
- Produced only a few atoms of copernicium-277, with a half life of 0.24 milliseconds
Internal view of the linear particle accelerator
Naming
- Named in honor of 16th century scientist and astronomer Nicolaus Copernicus
- Revolutionized scientific thinking with his heliocentric model of the solar system
Naming
Occurence
- Copernicium is a synthetically produced element that does not exist in nature
- Very little is known about this element
Occurence
Physical & Chemical Properties
- Based on its position, Copernicium should share some properties of a heavy metal like zinc, cadmium, or mercury
- However, it is thought to be unreactive and behave more like a noble gas, similar to radon
- Expected to be solid at room temperature
Isotopes
- Copernicium currently has four isotopes whose half lives are known
- Copernicium-285 is the most stable, and has a half life of about 30 seconds
- The short half lives of this element make it difficult to study
Radioactivity
- Since Copernicium is radioactive, it could be harmful to humans
- However, its instability causes it to decompose into other elements, so effects on human health are unknown
Radioactivity
Uses
Because only very small amounts have ever been produced, Copernicium is currently only used for scientific research
Uses
Possible Prospects
Because of its similarities to the radioactive noble gas radon, which has been used in the past for medical treatment, perhaps we will see Copernicium used in the future in similar applications.
Possible Prospects
