Classification
Nouns denoting substances.
Examples
- Nobelium is a synthetic element that has no stable isotopes and its chemical properties are not well established.
- The element nobelium was first synthesized in 1958 by bombarding curium with carbon ions at the Joint Institute for Nuclear Research in Dubna, Russia.
- Seven isotopes of nobelium are known, ranging in mass from 251 to 259 atomic mass units.
- Due to its highly radioactive nature, nobelium has no commercial applications and is only used in scientific research.
- The most stable isotope of nobelium, 259Nobelium, has a half-life of about 58 minutes, making it one of the longest-lived isotopes of the element.
