Introducing Hassium: A Super-Heavy Element
Hassium (pronounced HASS-ee-um) is a fascinating chemical element, though it is not found naturally on Earth. It belongs to a special group of elements known as ‘synthetic’ or ‘super-heavy’ elements. This means scientists create it in laboratories by smashing smaller atoms together at very high speeds. Hassium is extremely radioactive and exists for only a tiny fraction of a second before decaying into other elements. It has the atomic number 108, meaning every Hassium atom contains 108 protons in its nucleus.
Discovery and Naming
Hassium was first successfully created and identified in 1984 by a team of German scientists. The discovery took place at the Gesellschaft für Schwerionenforschung (GSI), which translates to the “Centre for Heavy Ion Research,” located in Darmstadt, Germany. The researchers achieved this by fusing lead-208 atoms with iron-58 atoms.
The element was named after the German state of Hesse, where the GSI laboratory is situated. The Latin name for Hesse is “Hassia,” from which “Hassium” is derived. This naming convention honours the geographical location of its discovery, much like many elements are named after places or scientists.
Quick Facts about Hassium
- Hassium is a synthetic element, meaning it does not occur in nature and must be created in a laboratory.
- It is incredibly radioactive, with its most stable known isotope, Hassium-270, having a half-life of only about 22 seconds. Most other isotopes exist for much less time.
- Hassium is classified as a super-heavy element due to its very high atomic number (108).
- Due to its extremely short existence and the small quantities produced, Hassium has no known practical uses outside of scientific research.
- Chemists predict that Hassium would behave chemically like a heavier analogue of osmium, belonging to Group 8 of the periodic table, alongside elements like iron, ruthenium, and osmium.
