Rutherfordium

Rutherford won many awards for his work as a scientist and teacher. He won the Nobel Prize for chemistry in 1908 and was knighted in 1914. In 1919 he became the Cavendish Professor of Physics at Cambridge. He was made Lord Rutherford of Nelson in 1931. Rutherford died at Cambridge on October 19, 1937. see also Bohr, Niels Marsden, Ernest Soddy, Frederick Thomson, Joseph John.

The claims for discovery and the naming of Element 104 are still in question. The Berkeley group proposes for the new element the name rutherfordium (symbol Rf), in honor of Ernest R. Rutherford, a New Zealand physicist. Meanwhile, the International Union of Pure and Applied Physics has proposed using the neutral temporary name, unnilquadium. 

Element 106 was created by the reaction 249Gf(180,4N)263X, which decayed by alpha emission to rutherfordium, and then by alpha emission to nobelium, which in turn further decayed by alpha between daughter and granddaughter. The element so identified had alpha energies of 9.06 and 9.25 MeV with a half-life of 0.9 +/- 0.2 s. 

An isotope of rutherfordium, JgRf, is formed by the bombardment of californium-249 by carbon-12. In the process, neutrons are emitted. The new isotope formed decays rapidly, emitting an alpha particle.

Scientists have succeeded in synthesizing about 25 elements that do not exist in nature. All except one of these (technetium, Z = 43) are members of period 7. All are very dense and radioactive. Many, such as Rutherfordium [Z = 104) and Bohrium (Z = 107), are quite short-lived, with no known applications outside of the laboratory. An exception is the element plutonium (Z = 94). Research several applications of this element, and the properties that make it well-suited for these uses. What risks are associated with plutonium Do the risks outweigh the benefits Justify your opinions.

Rutherfordium - the atomic number is 104 and the chemical symbol is Rf. The name derives from the English physicist Ernest Rutherford who won the Nobel prize for developing the theory of radioactive transformations. Credit for the first synthesis of this element is jointly shared by American scientists at the University of California lab in Berkeley, California under Albert Ghiorso and by Russian scientists at the JINR (Joint Institute for Nuclear Reactions) lab in Dubna, Russia under Georgi N. Flerov. The longest half-life associated with this unstable element is 10 minute Rf.

The chemical and physical properties of Unq (or rutherfordium) are homologous with the element hafnium ( jHf), located just above it in group 4 (fVB) in the periodic table. It was first claimed to be produced artificially by the Joint Institute for Nuclear Research (JINR) located in Dubna, Russia. The Russian scientists used a cyclotron that smashed a target of plutonium-242 with very heavy ions of neon-22, resulting in the following reaction Pu-242 + jjjNe-22 —> jj, Unq-260 + 4 n-1 (alpha radiation). The Russians named Unq-260 kurcha-tovium (Ku-260) for the head of their center, Ivan Kurchatov. (See details in the next section, History. )... 

There are no uses for unnilquadium (rutherfordium), except for high-energy nuclear-particle research.
