Results 1–7 of 7 for kalifornij
californium → kalifornij
Californium was discovered by Stanley G. Thompson, Kenneth Street Jr. and Albert Ghiorso (USA) in 1950. Named after the State and University of California, USA. It is synthetic radioactive metal. Powerful neutron emitter. Californium was made by bombarding curium with helium ions.
Californian soup → kalifornijska juha
Californian soup is a fungicide and insecticide chemical used for protection of plants, manufactured by boiling sulphur with slaked lime.
actinides → aktinoidi
Actinides (actinons or actinoids) are the fourteen elements from thorium to lawrencium inclusive, which follow actinium in the periodic table. The position of actinium is somewhat equivocal and, although not itself an actinide, it is often included with them for comparative purpose. The series includes the following elements: thorium (Th), protactinium (Pa), uranium (U), neptunium (Np), plutonium (Pu), amercium (Am), curium (Cm), berkelium (Bk), californium (Cf), einsteinium (Es), fermium (Fm), mendelevium (Md), nobelium (No) and lawrencium (Lr). Every known isotope of the actinide elements is radioactive. Traces of Pa, Np and Pu are consequently found, but only Th and U occur naturally to any useful extent.
berkelium → berkelij
Berkelium was discovered by Stanley G. Thompson, Albert Ghiorso and Glenn T. Seaborg (USA) in 1949. Named after Berkeley, a city in California, home of the University of California, USA. It is synthetic radioactive metal. Berkelium was made by bombarding americium with alpha particles.
dubnium → dubnij
Dubnium was discovered by workers at the Nuclear Institute at Dubna (USSR) and by workers at the University of California, Berkeley (USA) in 1967. The origin of the name dubnium is the Joint Nuclear Institute at Dubna, Russia, an institute heavily involved in the search for heavy elements. It is synthetic radioactive metal. Dubnium was made by bombarding californium-249 with a beam of nitrogen-15 ions. There are now five known isotopes of dubnium. The longest-lived is dubnium-262, with a half-life of 34 seconds.
lawrencium → lawrencij
Lawrencium was discovered by Albert Ghiorso, Torbjorn Sikkeland, Almon E. Larsh and Robert M. Latimer (USA) in 1961. Named in honour of Ernest O. Lawrence, inventor of the cyclotron. It is synthetic radioactive metal. Lawrencium was produced by bombarding a mixture of three isotopes of californium with boron-10 and boron-11 ions. Eight isotopes of lawrencium have been synthesized to date, with the longest-lived being lawrencium-256, which has a half-life of about 30 seconds.
rutherfordium → ruthefordij
Rutherfordium was discovered by workers at the Nuclear Institute at Dubna (USSR) and by workers at the University of California, Berkeley (USA) in 1964. Name in honour of Lord Rutherford, the physicist and chemist from New Zealand. It is synthetic radioactive metal. Rutherfordium was made by bombarding californium-249 with beams of carbon-12 and 13. Six isotopes of rutherfordium have so far been identified. Rutherfordium-261, the longest-lived, has a half-life of 62 seconds.
