Discovery of Copernicium
In the early 1990s, scientists began to synthesize an element that would later be named Copernicium. The first to discover this element was a group of German scientists led by Sigurd Hofmann from the Institute for Heavy Ion Research at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt.
Copernicium’s synthesis was achieved by firing accelerated zinc ions at a target made of lead-208. The resulting isotopes were then separated and analyzed to confirm the existence of new elements.
Copernicium has no stable isotopes and is only produced in the lab. The most stable isotope, Copernicium-285, has a half-life of only 29 seconds.
This means that it takes less than a minute for half of the atoms of this isotope to decay. The other isotopes of Copernicium have even shorter half-lives, lasting only a few milliseconds.
Naming of Copernicium
In 2009, the IUPAC (International Union of Pure and Applied Chemistry) officially recognized the discovery of element 112 and granted it a permanent name: Copernicium. The name was chosen to honor the astronomer Nicolaus Copernicus, who first proposed the theory that the sun, not the earth, was the center of our solar system.
This theory, known as the heliocentric model, revolutionized astronomy and laid the foundation for modern astronomy.
Position of Copernicium in the Periodic Table
Copernicium is a member of Group 12 in the periodic table, also known as the zinc group. This group consists of the elements zinc, cadmium, and mercury, which share similar chemical properties.
Like the other elements in Group 12, Copernicium has a filled d-shell and exhibits mostly a +2 oxidation state.
Copernicium is also a member of Period 7, which consists of elements with progressively larger atomic numbers.
This period includes many of the heaviest and most unstable elements, including the actinide and transactinide series. Copernicium is located in the d-block of the periodic table, which contains the transition metals.
These elements are characterized by their ability to form various oxidation states and to exhibit metallic properties such as ductility, conductivity, and luster.
Properties of Copernicium
Due to its extremely short half-life, Copernicium has almost no practical applications and has only been studied for its scientific value. As a synthetic element, it is difficult to produce in large quantities and is very radioactive.
Its properties have only been inferred from its position in the periodic table and the behavior of other elements with similar characteristics. Based on its position, it is expected that Copernicium would have a metallic luster and conduct electricity and heat.
It is predicted to have a density of around 23.7 g/cm3, which is similar to that of silver. It is also expected to be very reactive, easily forming chemical compounds with other elements, especially those from Groups 16 and 17.
However, there is not enough data to confirm or refute any of these predictions.
Significance of Copernicium
The discovery and naming of Copernicium have added to the growing body of knowledge about elements and their properties. It has helped to fill in the gaps in the periodic table and has provided insight into the behavior of heavy and unstable elements.
Copernicium has also contributed to our understanding of nuclear physics and the nature of matter. Understanding the properties of heavy elements such as Copernicium is vital for future research and technological advances.
These elements have the potential to be used in nuclear power plants, as catalysts, and in other industries. Copernicium has also been used to study the nature of superheavy elements and the limits of the periodic table.
Conclusion
In conclusion, the discovery of Copernicium and its naming after the great astronomer Nicolaus Copernicus serve as a testament to human ingenuity and our desire to understand the world around us. Despite its extremely short half-life and lack of practical applications, Copernicium has contributed to our understanding of the properties of heavy and unstable elements.
Its study has opened up new avenues for research in nuclear physics and the nature of matter. As we continue to explore the periodic table and the behavior of elements, it is likely that we will discover new and exciting properties that will help us to better understand the world we live in.
Copernicium Physical Properties

Color/Appearance, Odor: Copernicium’s appearance is unknown since it has never been observed in its pure metallic form. Since it is a member of the zinc group, it is likely to have a metallic luster similar to zinc and other elements in the group.
However, its exact color and appearance remain unknown. Similarly, since it is a synthetic element that has never been synthesized in large quantities, its odor is unknown.
Boiling Point, Melting Point, and Density: Copernicium’s boiling point, melting point, and density are also unknown due to its unstable nature. Theoretical calculations suggest that Copernicium would have a boiling point higher than that of zinc, which boils at 907 C.
Since Copernicium’s melting point and density have not been experimentally confirmed, their values remain theoretical as well. State at Room Temperature, Malleability: Due to its short half-life and high radioactivity, it is not possible to observe Copernicium at room temperature.
However, based on its position in the periodic table, it is predicted to be a solid at room temperature. Its malleability is also unknown since it has never been observed in a pure metallic form.
