Why is thorium named thorium?
Thorium is named after Thor, the Scandinavian god of war.
What is thorium and its uses?
Applications of Thorium As thorium is radioactive, its uses mainly lie in nuclear fuel applications. It is helpful in radiometric dating. Used as an alloying element in magnesium, to coat tungsten wire in electrical equipment. Used in manufacturing of lenses for cameras and scientific instruments.
What is the half-life of U 232?
69-year
U-232 decays with a 69-year half-life through 1.9-year half-life Th-228 to Tl-208, which emits a 2.6 MeV gamma ray upon decay.
How is thorium 232 used?
The most stable isotope of thorium, Th-232, has a half-life of 14 billion years, according to the EPA. Thorium had been used since 1885 in gas mantles, which provide the light in gas lamps, according to Los Alamos. Due to its radioactivity, the element has been replaced by other nonradioactive rare-earth elements.
Who discovered plutonium?

Plutonium/Discoverers
On March 21, 1942, the chemical element with the atomic number 94 was given the name plutonium, after the dwarf planet Pluto. Discovered by Glenn Seaborg, Edwin McMillan, and their colleagues, plutonium is a radioactive element that can be used to both create and destroy.
How is U 232 formed?
Significant quantities of U-232 are also produced when reactor fuel contains thorium impurities. Either an (n, 2n) reaction in Th-232 or an (n,y) reaction in Th-230 produces Th-231 which rapidly beta decays to Pa-231. The Pa-231 can undergo an (n,y) reaction to become Pa-232 which then beta decays to U-232.
Is the 232 fissile?
Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor.
How does PubChem work on the periodic table?
Finally, IUPAC assigns collective names (lanthanoids and actinoids) and group numbering (1 to 18) and has investigated the membership of the group 3 elements. PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable.
How did thorium get its name on the periodic table?
Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties. For more information on the Visual Elements image see the Uses and properties section below. Thorium is named after Thor, the Scandinavian god of war. A vertical column in the periodic table.
How did the element protactinium get its name?
The name “protactinium” comes from adding the Greek protos meaning first, before the word ” actinium .” In 1871, Dmitri Mendeleev predicted the existence of an element between thorium and uranium. In 1900, William Crookes isolated protactinium from uraniu.
Which is the rarest element on the periodic table?
Protactinium-233 results from the decay of thorium-233 as part of the chain of events used to produce uranium-233 by neutron irradiation of thorium-232. Protactinium is one of the rarest and most expensive naturally occurring elements.
