An artificially produced radioactive element with atomic number 110. Isotopes having mass numbers ranging from 267 to 281 are known, with the most stable isotope (Ds-281) having a half-life of about 10 seconds.
A radioactive chemical element with a very short half-life: it is a transactinide usually produced by bombarding lead with high-energy nuclear particles: symbol, Ds; at. no. 110
A synthetic radioactive element, first produced by bombarding lead atoms with nickel atoms. It has a mass number of 281, and its most stable isotope has a half-life of over one minute. Atomic number 110.
