Darmstadtium is a chemical element with the symbol Ds and atomic number 110. It is an extremely radioactive synthetic element. The most stable known isotope, Darmstadtium-281, has a half-life of approximately 12.7 seconds. It was first created in 1994 by the GSI Helmholtz Centre for Heavy Ion Research near the city of Darmstadt, Germany, after which it was named.
It is a d-block transactinide element. It is a member of the 7th period and is placed in the group 10 elements, although no chemical experiments have yet been carried out to confirm that it behaves as the heavier homologue to platinum in group 10 as the eighth member of the 6d series of transition metals. It is calculated to have similar properties to its lighter homologues, nickel, palladium, and platinum.
Characteristics of Darmstadtium
- It is a man-made element of which only a few atoms have ever been created. It was created in a heavy ion accelerator using atoms of lead & nickel. Thus, most of its properties have been predicted.
- It is a d-block transactinide element in the periodic table and a member of the 7th period which is placed in group 10 elements.
- It was predicted that this element contains similar properties as that of its homologues, palladium, nickel, and platinum.
- Ds is expected to be solid at room temperature and a very heavy metal with a density of 34.8 g/cm3
- The element has no naturally occurring or stable isotopes. The most stable known isotope is darmstadtium whose life is expected be approximately 10 seconds.
