| This element was first synthesized on February 19, 1955, at the University of California in Berkley by scientist who bombarded the element einsteinium with alpha particles. |
| Glenn Seaborg, Albert Ghiorso, Gregory Choppin, Stanley Thompson, and Bernard Harvey synthesized the element. |
| The first sample of mendelevium was only seventeen atoms. |
| The proposed experiment produced only one atom at a time of the sample, made by calculating the number of atoms of material expected times the intensity of the ion beam used, times the bombardment per half-life. |
| Using Ghiroso's recoil technique, the sample was first synthesized. |
| While the group of scientists did not actually detect the sample of mendelevium, the spontaneous fission events that the synthesis produced indicated its existence in experiments. |
| There are sixteen known isotopes of mendelevium. |
| The most stable isotope is Md-258, which has a half-life of only 51.5 days. |
| All but three of the remaining isotopes have a half-life of less than an hour and a half. |
| Most of those isotopes have half-lives of less than five minutes. |
| Mendelevium also has five meta states. |
| It is a radioactive element that undoes spontaneous fission. |
| Based on observation of trace particles, mendelevium is believed to create a divalent metal. |
| This theory first predicted by Johansson and Rosengren in 1975, nearly twenty years after mendelevium was first observed. |
| Mendelevium was the first element to allow researchers to observe a trivalent state that was stable in an aqueous solution. |
| Due to its rarity, there are no known commercial applications for the element. |
