Very few properties of rutherfordium or its compounds have been measured; this is due to its extremely limited and expensive production [70] and the fact that rutherfordium (and its parents) decays very quickly. A few singular chemistry-related properties have been measured, but properties of rutherfordium metal remain unknown and only ...
Rutherfordium (104 Rf) is a synthetic element and thus has no stable isotopes. A standard atomic weight cannot be given. The first isotope to be synthesized was either 259 Rf in 1966 or 257 Rf in 1969. There are 17 known radioisotopes from 252 Rf to 270 Rf (three of which, 266 Rf, 268 Rf, and 270 Rf, are unconfirmed) and several isomers.
Group 4 is the second group of transition metals in the periodic table. It contains only the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). ). The group is also called the titanium group or titanium family after its lightest me

Ivanka Trump wore diamond jewelry with a total value of $1.1 million at Donald Trump's inauguration. She wore the jewelry with gowns designed by Oscar de la Renta and Givenchy.
The alpha daughter rutherfordium-259 and granddaughter nobelium-255 had previously been synthesised and the properties observed here matched with those previously known, as did the intensity of their production. The cross-section of the reaction observed, 0.3 nanobarns, also agreed well with theoretical predictions. These bolstered the ...
