| The transfermium elements are those elements with atomic numbers greater than 100, the atomic number for fermium. |
| All isotopes of fermium are radioactive, with fermium-257 having the longest half life, 20.1 hours. |
| Made in the 1952 detonation of the first thermonuclear bomb, the element fermium has since sat in a corner of the periodic table where few tools of chemistry reach. |
| Besides probing fermium further, the team plans next to study element number 101, mendelevium, Backe says. |
| Therefore, all studies of fermium chemistry have been done on the tracer scale. |
| Only if mass-produced could fermium pose a threat to human health. |
