What is rutherfordium?
Rutherfordium is a synthetic chemical element with symbol Rf and atomic number 104, named after physicist Ernest Rutherford. As a synthetic element, it is not found in nature and can only be created in a laboratory.
Is rutherfordium a D block element?
Rutherfordium. In the periodic table of the elements, it is a d-block element and the second of the fourth-row transition elements. It is a member of the 7th period and belongs to the group 4 elements. Chemistry experiments have confirmed that rutherfordium behaves as the heavier homologue to hafnium in group 4.
How many isotopes of rutherfordium are there?
Rutherfordium has no stable or naturally occurring isotopes. Several radioactive isotopes have been synthesized in the laboratory, either by fusing two atoms or by observing the decay of heavier elements. Sixteen different isotopes have been reported with atomic masses from 253 to 270 (with the exceptions of 264 and 269).
How does rutherfordium decay?
It decays through spontaneous fission. Rutherfordium is produced artificially and only small amounts have been made. The Dubna scientists produced it by bombarding plutonium with accelerated 113 to 115 MeV neon ions. The Berkeley team produced four isotopes by bombarding 249 Cf with 12 C nuclei of 71 MeV, and 13 C nuclei of 69 MeV.

Rutherfordium: Discovery
The discovery of Rutherfordium is said to be controversial as there is confusion between who discovered rutherfordium. The discovery was first reported in 1964 by a group of scientists in Dubna, Russia. The Joint Institute of Nuclear Research at Dubna, Russia, U.S.S.R.
Things To Remember
Rutherfordium is an element named in honour of Ernest Rutherford, the eminent scientist of Britain. It is not available in nature and hence is called a synthetic element.
How was Rutherfordium Discovered?
There are some controversies involved with who discovered rutherfordium. A group of scientists in Dubna, Russia first reported about its discovery in the year 1964. Russian scientists in the Joint Institute of Nuclear Research at Dubna, Russia, U.S.S.R. declared the discovery of element 104. They named the element as kurchatovium, with the symbol Ku following the name of a Soviet Nuclear Physicist Igor Kurchatov. An isotope, 260Rf was produced that had 0.3 seconds of half-life. Then they changed the half-life to 0.15 seconds.
What is Rutherfordium named after?
Rutherfordium is a synthetic element, named in honour of eminent scientist of Britain, Ernest Rutherford. It is a synthetic element that means it is not available in nature. You can prepare it in the laboratory.
What is the half life of 104?
In Dubna, the Soviet researchers bombarded Plutonium 242 along with the ions of neon 22. They made a declaration of obtaining an isotope of element 104 whose mass number is 260 and half-life of 0.3 seconds. Then they performed numerous experiments on the isotope newly discovered and claimed that it behaved the same way as they predicted for it. Next time, when they used a more advanced method for half-life measurement, it came out different from the earlier one. They found the half-life of the element is 0.1 seconds, not 0.3 seconds as they reported earlier. The mismatch in results creates doubt on the chemical experiments.
How long does Rutherfordium decay?
12 isotopes of Rutherfordium are recognised along with their half-lives. The most stable one among the 12 isotopes is 265Rf having a half-life of about 13 hours and decays through spontaneous fission.
What is the mass number of Curium 248?
This isotope has a mass number of 261and half-life 70 seconds .
What is the name of the isotopes that are produced by decaying?
alpha particles and detect the products produced on decaying, which are known as nobelium isotopes.
When did the Dubna gang regenerate the isotopes?
In the year of 1969 , a team of American researchers at the Lawrence Radiation Laboratory of the University of California, Berkeley attempted to regenerate the result of the isotope identified by the Dubna gang. They announced that they have been able to identify the isotopes of the element which are different from the U.S.S.R. lab. This time, they had been able to produce four isotopes of Rutherfordium by following a different method. The controversy is, whether they produced 260Rf or not, is not confirmed in the report.
