Darmstadtium facts
- Before it was named, element 110 was known by the temporary systematic name ununnilium.
- Darmstadtium is one of several elements named after a city, along with berkelium, dubnium and hafnium, from Hafnia, the Latin name for Copenhagen.
- Darmstadtium (Ds) has atomic number 110. It was discovered in 1994.
Position in the periodic table
Darmstadtium is element 110, in period 7 and group 10 of the periodic table, in the d-block.
Uses of Darmstadtium
Darmstadtium has no uses outside research. Only a small number of atoms have been made, and even its longest-lived known isotopes decay within seconds, so its chemical properties have not yet been measured. Calculations predict that it should behave like platinum, the element above it in group 10.
Who discovered Darmstadtium?
A team led by Sigurd Hofmann at GSI in Darmstadt, Germany, first made darmstadtium in 1994 by bombarding lead with nickel ions. It is named after the city of Darmstadt, home of GSI.
Where does the name come from?
Darmstadtium is named after Darmstadt, Germany, the city where scientists at the GSI research center first created the element in 1994 by fusing lead and nickel nuclei.

The electron configuration of Darmstadtium (Ds) is [Rn] 5f14 6d8 7s2. Its 110 electrons are arranged in shells as 2, 8, 18, 32, 32, 16, 2.
How many protons, neutrons and electrons does Darmstadtium have?
A neutral Darmstadtium atom has 110 protons and 110 electrons. Most Darmstadtium atoms have about 171 neutrons: the atomic mass rounded to 281, minus the atomic number 110.
How many valence electrons does Darmstadtium have?
Darmstadtium has 2 valence electrons, counting the electrons in its outermost s subshell. Like most transition metals, it can also use d electrons in bonding.
What is the molar mass of Darmstadtium?
The molar mass of Darmstadtium is 281 g/mol. This is the same number as its atomic mass, 281 u.
Is Darmstadtium a metal?
Darmstadtium is a synthetic superheavy element, so too few atoms have been made to measure whether it behaves as a metal.
Is Darmstadtium radioactive?
Yes. Darmstadtium has no stable isotopes, so all of its atoms are radioactive and eventually decay into other elements.
Where is Darmstadtium on the periodic table?
Darmstadtium is element 110, in period 7 and group 10 of the periodic table, in the d-block.
