Periodic Table appDiscovery date1949Discovered byStanley Thompson, Albert Ghiorso, and Glenn SeaborgOrigin of the nameBerkelium was named after the town Berkeley, California, where it was first made.Allotropes.
Who discovered Element 104?
Igor KurchatovSoviet scientists at the Joint Institute for Nuclear Research at Dubna, Russia, U.S.S.R. , announced in 1964 the discovery of element 104, which they named kurchatovium, symbol Ku (for Igor Kurchatov, a Soviet nuclear physicist).
Which element is used to paint the skin to prevent infection from cuts?
iodineThis solution was also used to treat wounds in the American Civil War. The antimicrobial properties of iodine were first demonstrated in 1882 by Davaine6. In the First World War, iodine was found by Alexander Fleming to reduce the incidence of gas gangrene in the wounds of soldiers when compared to carbolic acid7.
What is the most expensive element in the world?
franciumThe most expensive natural element is francium. Although francium occurs naturally, it decays so quickly that it cannot be collected for use. Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion U.S. dollars for it.
Why is californium dangerous?
Californium is intensely radioactive and fissile (which means that it is unstable) and thus, it is very dangerous. … Since it is a very strong neutron emitter, californium-252 is the most dangerous and harmful of all this element’s isotopes.
Is californium man made?
Californium is a man-made element that is formed from curium or plutonium. Californium has several uses, and in this lesson, we will go through these uses.
Why is the symbol for the transuranic element rutherfordium RF instead of RU?
Why is the symbol for the transuranic element Rutherfordium Rf instead of Ru? Transuranic elements are the chemical elements having atomic number greater than 92. … These elements do not occur naturally, but they are created artificially.
How did lanthanum get its name?
Word origin: Lanthanum is named after the Greek word lanthanein, which means to escape notice. Discovery: Swedish chemist Carl Gustaf Mosander extracted lanthanum oxide, or lanthana, from an impure cerium nitrate in 1839. In 1923, a relatively pure form of lanthanum was isolated.
What is berkelium used for in the world?
Uses of berkelium Due to its relatively long half-life and microgram quantity availability, 249Bk is used extensively as a target to synthesize heavier elements by charged particle bombardment.
How was berkelium created?
The eighth member of the actinide transition series, berkelium was discovered in December 1949 by Thompson, Albert Ghiorso, and Glenn Seaborg, and was the fifth transuranium element synthesized. It was produced by cyclotron bombardment of milligram amounts of 241Am with helium ions at the Berkeley Radiation Laboratory.
Is berkelium radioactive?
Berkelium is one of 15 actinides, elements with atomic numbers 89 to 103. Because these rare, heavy metal isotopes are radioactive, they are difficult to study.
What 4 elements are named after planets?
The four elements named after planets are mercury, uranium, neptunium, and plutonium.
How did Bohrium get its name?
Word Origin: Bohrium was named for Danish physicist Niels Bohr. For a time, it was known as nielsbohrium with the symbol Ns.
What is californium named after?
Origin of the name Californium is named for the university and state of California, where the element was first made.
How much does berkelium cost?
For this study, the berkelium was created by Oak Ridge National Laboratory using its High Flux Isotope Reactor, a process that cost about $500,000 and resulted in 13 milligrams for Albrecht-Schmitt and half a microgram for Braley.
Is rutherfordium man made?
Rutherfordium is a synthetic chemical element with the symbol Rf and atomic number 104, named after New Zealand physicist Ernest Rutherford. As a synthetic element, it is not found in nature and can only be created in a laboratory.
Who found berkelium?

Is rutherfordium radioactive?
Rutherfordium is a highly radioactive chemical element. His most stable isotope Rf 265 has an half like of approximately 13 hours. Nine of its isotopes are known.
What is the symbol of uranium?
Is beryllium stable?
Beryllium is the only stable light metal with a relatively high melting point. Although it is readily attacked by alkalies and nonoxidizing acids, beryllium rapidly forms an adherent oxide surface film that protects the metal from further air oxidation under normal conditions.
