Darmstadtium
chemical element with atomic number 110 / From Wikipedia, the free encyclopedia

The element is named in honor of German city Darmstadt.
Darmstadtium is a radioactive element that does not exist in nature. It has to be made. The isotopes with an atomic mass from 267 to 273 have very short half-lifes. The half life of these isotopes is measured in milliseconds. Isotopes of darmstadtium with an atomic mass of 279 and 281 were synthesised after the other isotopes. Ds-279 and Ds-281 decay more slowly. The isotope with an atomic mass of 279 has a half life of 180 milliseconds and Ds-281 has a half life of 11.1 seconds.
No uses for darmstadtium are known. What darmstadtium looks like is not known because not enough has been made to see it with human eyesight.
