any except for bromine, Mercury, nitrogen, oxygen, fluorine, helium, neon, argon, krypton, xenon, radon, hydrogen, chlorine. And then we are unsure of the states of (rutherfordium, dubnium, seaborgium, bohrium, hassium, meiternium, darmstadium, roentgenium, copernicium, flevourium, and livermorium. Hope this helps.
Darmstadtium was discovered by a team of scientists led by Peter Armbruster and Gottfried Münzenberg at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany in 1994. It was named after the city of Darmstadt.
The element's name is darmstadtium. It is named after the place of its discovery in Germany.
The chemical element, Darmstadium, has an atomic number of 110. That means that it has 110 protons in it. It's longest-lived isotope, at 3.7 minutes, is 281bDs. That means that this isotope has 281 - 110 = 171 neutrons in it.
