The mendelevium atoms are then trapped in a gas atmosphere ( frequently helium ), and a gas jet from a small opening in the reaction chamber carries the mendelevium along.

Owing to the small amounts of produced mendelevium and all of its isotopes having relatively short half-lives, there are currently no uses for it outside of basic scientific research.

In 1975, Johansson and Rosengren examined the measured and predicted values for the Thermochromatographic studies with trace quantities of mendelevium by Zvara and H�bener from 1976 to 1982 confirmed this prediction.

In 1973, mendelevium ( I ) was reported to have been produced by Russian scientists, who obtained it by reducing higher oxidation states of mendelevium with samarium ( II ).

All of the remaining mendelevium isotopes have half-lives that are less than an hour, and the majority of these have half-lives that are less than 5 minutes.

The solvent extraction then proceeds, and while the trivalent and tetravalent lanthanides and actinides remain on the column, mendelevium ( II ) does not and stays in the hydrochloric acid.

Mendelevium-256, the chemically most important isotope of mendelevium, decays through electron capture 90.7 % of the time and alpha decay 9.9 % of the time.
