atomic number 110

Definition
Noun: A synthetic, highly radioactive metallic element in the transuranic series. It is not found naturally and is produced artificially in particle accelerators. It is a transition metal and a member of the platinum group metals.
Usage
This term is used exclusively in scientific contexts, particularly in chemistry and physics, to denote the chemical element with 110 protons in its nucleus. Its official systematic name, prior to being named, was "ununnilium" (symbol: Uun). It is now named darmstadtium (symbol: Ds).
Examples
- The discovery of atomic number 110 was officially confirmed in 2001.
- Scientists synthesized atoms of atomic number 110 by fusing nickel and lead nuclei.
- Darmstadtium, element with atomic number 110, has extremely short-lived isotopes.
Advanced Usage
- In systematic nomenclature: The temporary name "ununnilium" (from Latin for one and for zero) was used for atomic number 110 before its permanent name was assigned.
- In research: Due to its rapid radioactive decay, the chemical properties of atomic number 110 are inferred from its position in the periodic table rather than from direct experiment.
Variants and Related Words
- Darmstadtium (Ds): The permanent name for the element with atomic number 110, named after the city of Darmstadt, Germany, where it was discovered.
- Ununnilium (Uun): The former temporary systematic IUPAC name.
- Transuranic element: Any chemical element with an atomic number greater than 92 (uranium). Atomic number 110 is a transuranic element.
- Synthetic element: An element not found in nature and produced artificially.
Synonyms
- Darmstadtium
- Ds (chemical symbol)
- Element 110
- (Historically) Ununnilium
