Hassium Element in Periodic Table | Atomic Number Atomic Mass

Hassium

Hassium Element:

Hassium is a radioactive synthetic chemical element.It is named after the German state of Hesse. Its atomic number is 108 and represented by the symbol Hs. The element does not occur naturally and it is created artificially in the laboratory by the bombarding lead with iron atoms. In the periodic table it is a d-block transactinide element. It is belongs to the group 8 elements and a member of period 7 in the periodic table. Hassium contains 12 isotopes with known half-lives with mass number from 263 to 277 (with the exceptions of 272, 274, and 276), which are synthesized in the laboratory. The most stable isotope is 270Hs with a half-life of approximately 10 seconds.

Uses Of Hassium Element:

  • Only a few atoms of Hassium have ever been produced and its isotopes have very short half-lives. For this reason, at present it is only used in scientific research.
