  It's Elemental - The Element Nobelium
They produced this new element, which they named nobelium, by bombarding a target of curium-244 with ions of carbon-13 with a device called a cyclotron.
They were unable to produce any isotope of nobelium with a half-life of 10 minutes, but were able to produce nobelium-254, with a half-life of three seconds, by bombarding curium-246 with carbon-12.
Since only tiny amounts of nobelium have ever been produced, there are currently no uses for it outside of basic scientific research.

Nobelium, also known as unnilbium, is a synthetic element in the periodic table that has the symbol No and atomic number 102.
Nobelium (named for Alfred Nobel) was first synthesized by Albert Ghiorso, Glenn T. Seaborg, John R. Walton and Torbjørn Sikkeland in April 1958 at the University of California, Berkeley.
Nobelium was the most recent element "of which the news had come to Harvard" when Tom Lehrer wrote "The Elements Song" and was therefore the element with the highest atomic number to be included.

Nobelium was unambiguously discovered and identified in April 1958 at Berkeley by A. Ghiorso, T. Sikkeland, J.
Earlier in 1957 workers of the U.S., Britain, and Sweden announced the discovery of an isotope of Element 102 with a 10-min half-life at 8.5 MeV, as a result of bombarding 244Cm with 13C nuclei.
On the basis of this experiment the name nobelium was assigned and accepted by the Commission on Atomic Weights of the International Union of Pure and Applied Chemistry.

  Nobelium (No)   (Site not responding. Last check: )
Nobelium is a radioactive metallic element and is one of the transuranium elements in the actinide series.
However, the first confirmed discovery of a nobelium isotope was in 1958 by a team of scientists at the Lawrence Radiation Laboratory in Berkley, California.
The chemical properties of nobelium are unknown; however, since it is an actinide, the properties should resemble those of the rare earth elements.

(Alfred Nobel, discoverer of dynamite) Nobelium was unambiguiously discovered andidentified in April 1958 at Berkeley by A. Ghiorso, T. Sikkeland, J.R. Walton, and G.T.Seaborg, who used a new double-recoil technique.
In 1957 workers in the United States, Britain, and Sweden announced the discovery of anisotope of element 102 with a 10-minute half-life at 8.5 MeV, as a result of bombarding244Cm with 13C nuclei.
The acceptance of the name was premature because both Russian and American efforts nowcompletely rule out the possibility of any isotope of Element 102 having a half-life of 10min in the vicinity of 8.5 MeV.

It is a metal of the actinide series in group IIIb of the periodic table.
Nobelium was the tenth transuranium element to be discovered.
It was first produced and detected in Apr., 1958, by Albert Ghiorso, TorbjOrn Sikkeland, John R. Walton, and Glenn T. Seaborg at the Univ. of California at Berkeley; they used a heavy-ion linear accelerator to bombard a mixture of curium-244 and curium-246 with carbon-12 ions, producing nobelium-254 (half-life 55 sec).

 Nobelium (No) - Chemical properties, Health and Environmental effects
Nobelium is the second transferium element with the most stable isotope 259Md having a half-life of 58 minutes.
The transferium elements do not exist in nature and they have very unstable nuclei, so they are quite hard to make and detect.
Nobelium doesn’t occur naturally, it has not yet been found in the earth’s crust and it’s so unstable that any amount formed would decompose to other elements very quickly.

They irradiated a target of Cm 244, Cm 246 and Cm 248 with Carbon ions, obtaining an isotope with mass number between 251 and 255, but with atomic number considered to be 102.
Only in 1963 they were able to report the detection of No 256 through the irradiation of U 238 with Neon ions and using a method similar to the other research groups.
The name and symbol Nobelium (No) was ratified by the International Union of Pure and Applied Chemistr (IUPAC) Council meeting in Geneva during August 1997 (see "Naming the transfermium elements" on the Mendelevium page).
