Darmstadtium is a chemical element with atomic number 110, denoted by the symbol "Ds". It is classified as a metal and is solid at room temperature. Although the life of the first atoms produced was only 1 / 100th of a second, scientists were able to produce heavier and more stable versions. Darmstadtium-281, the most stable known isotope of darmstadtium, a synthetic element, has a half-life of about 12.7 seconds. The Darmstadtium element was first created in 1994 at the Helmholtz Heavy Ion Research Center near Darmstadt, Germany, and was later named after this city. Only a few atoms have been produced so far. It is a highly radioactive metal. It is thought to have physical properties similar to nickel, palladium, and platinum. Except for its nuclear properties, no properties of darmstadtium or its compounds have been calculated. The reasons for this are its extremely limited production and the rapid decay of its isotopes.
Since Darmstadium is a synthetic element, it is not found free in the environment. Darmstadtium is artificially produced by fusing a nickel and lead atom together, a difficult reaction that occurs only when nickel atoms are reflected at a very specific speed to the lead target. Researchers fire billions of nickel atoms at a lead target over several days in order to synthesize one atom of the element.
This process results in only a few atoms of the element being produced. Due to the half-life of only 270 microseconds, no observable darmstadtium specimen can be produced.
