Such experiments have shown, for example, that elements 104 and 105 - rutherfordium and dubnium - deviate somewhat from the behaviour expected from their position on the periodic table, whereas element 106 (seaborgium) does not.2 These irregularities stem from changes to the electron energies ...
Practical uses for super-heavy elements, such as rutherfordium (Rf), seaborgium (Sg), hassium (Hs), copernicium (Cn) and dubnium (Db), are not featured in the new periodic table. These short-lived radioactive elements cannot be found in nature and are considered to be used mainly for atomic research.

Often shortened to SHE, the term 'superheavy' refers to elements with an atomic number that's heavier than rutherfordium (element 104). They aren't naturally occurring, as they suffer radioactive decay when exposed to lighter elements. This means that scientists are restricted to creating them in labs.
Over the course of 30 years, his inventions contributed to the discovery of americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, rutherfordium, dubnium and seaborgium. Seaborgium was named after his colleague Glenn Seaborg, a nuclear scientist.
The experiments that refined and characterized a few atoms apiece of elements 104 (rutherfordium) to 108 (hassium) -- each decaying within tens of seconds at most -- are breathtaking examples of ultra-sensitive chemical analysis. But the methods used to make the elements in the first place, bombarding ...
In the end, the IUPAC decided that the US could have elements 104 (rutherfordium) and 106 (seaborgium), Russia would be awarded 105 (dubnium) and 107 (bohrium), and Germany got the naming rights to 108 (hassium) and 109 (meitnerium). That decision was taken in 1997 and the refreshed naming ...

Those superheavy nuclei that have been created artificially have decay lifetimes between nanoseconds ...
According to the periodic law of the elements, rutherfordium (element 104) and dubnium (105) should behave like the elements directly above them in the periodic table - hafnium (72) and tantalum (73). Instead, Ken Czerwinski found rutherfordium has more in common with plutonium (94) while dubnium is like protactinium ...
Discovery: There has been some controversy over the discovery of rutherfordium. It was first reported by a team of scientists in Dubna, Russia, in 1964. They identified and isotope, 260Rf, with a reported half-life of 0.3 seconds. They later changed the report of their findings to say that 260Rf had a half-life of ...
This week's element is rutherfordium, a synthetic transition metal that has the atomic symbol Rf and atomic number, 104. Its name was inspired by physicist Ernest Rutherford, who was born in New Zealand. Although Lord Rutherford was famously quoted as saying, "All science is either physics or stamp ...

... Cambridge's centre of experimental physics. After his death in 1937, he was honoured by being interred with Britain's greatest scientists near Sir Isaac Newton's tomb in Westminster Abbey.
Practical uses for super-heavy elements, such as rutherfordium (Rf), seaborgium (Sg), hassium (Hs), copernicium (Cn) and dubnium (Db), are not featured in the new periodic table.

In the end, Americans named element 104 rutherfordium, in honor of British chemist and physicist Ernest Rutherford. Element 105, dubnium, is named for the Russian town of Dubna.
An Iupac group was convened to adjudicate in 1992, but it wasn't until 1997 that a resolution was reached and the periodic table gained rutherfordium. As consolation, the Russians got to call element 105 dubnium. Iupac also had to deal with priority ...
