Noun
a radioactive transuranic element synthesized by bombarding curium with carbon ions; 7 isotopes are known

Chemistry experiments have confirmed that nobelium behaves as a heavier homolog to ytterbium in the periodic table. Source: Internet
A total of twelve nobelium isotopes are known to exist; the most stable is 259 No with a half-life of 58 minutes, but the shorter-lived 255 No (half-life 3.1 minutes) is most commonly used in chemistry because it can be produced on a larger scale. Source: Internet
However, if a direct "catcher" gold foil is used, the process is complicated by the need to separate out the gold using anion-exchange chromatography before isolating the nobelium by elution from chromatographic extraction columns using HDEHP. Source: Internet
Long-lived isotopes of nobelium and isotopes of lawrencium (and of heavier elements) have relatively short half-lives. Source: Internet
Given this, it is probable that no nobelium was actually produced in this experiment. Source: Internet
