Thorium (Th) - Chemical properties, Health and ...

Thorium. When pure, thorium is a silvery white metal which is air-stable and retains its lustre for several months. When contaminated with the oxide, thorium slowly tarnishes in air, becoming grey and finally black. Thorium oxide has a melting point of 3300°C, the highest of all oxides. The thorium series begins with thorium-232 and ends with the stable nuclide lead-208. The neptunium series is named for its longest-lived member, neptunium-237; it ends with bismuth-209. The uranium series begins with uranium-238 and ends with lead-206. The actinium series, named for its first-discovered member, actinium-227, begins with ...

It's Elemental - The Element Thorium

Thorium is used as an alloying agent to improve magnesium's strength at high temperatures. Thorium is also used to coat tungsten filaments used in electronic devices, such at television sets. When bombarded with neutrons, thorium-232 becomes thorium-233, which eventually decays into uranium-233 through a series of beta decays. Uranium-233 is a ...

Family planning | UNFPA - United Nations Population Fund

Access to safe, voluntary family planning is a human right. Family planning is central to gender equality and women's empowerment, and it is a key factor in reducing poverty. Yet in developing regions, an estimated 232 million women who want to avoid pregnancy are not using safe and effective family planning methods, for reasons ranging from lack of access to information or services to lack ... She grew up in a close family where the deep love of parents and children for God, neighbor and each other was the very heart of the home and family life.

Protactinium - Element information, properties and uses ...

Even though protactinium has a lower atomic weight than thorium it should be placed after thorium because of its greater atomic number. But it appears that Mendeleev's brief predictions were broadly fulfilled since the element does indeed show an analogy with tantalum in forming Pa 2 O 5 as its highest and most stable oxide. All family chimes in wishing her well and hope she enjoys my the gift as well and how lucky she is to have such a nice DIL who thinks of her. ( I'm sure that made her blood boil after the bullshit she has caused) Of course she has to place nice and publicly thank me, my husband and our kids. All of them.

Protactinium - Wikipedia

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. It is an undesired intermediate product in thorium-based nuclear reactors and is therefore removed from the active zone of the reactor during the breeding process. 1638 54th Ave N # 232, Nashville, TN 37209 is currently not for sale.

Thorium-233 forms when thorium-232 absorbs a neutron. Thorium-233 has a half-life of about 22 minutes and decays into protactinium-233 through beta decay. Protactinium-233 has a half-life of about 27 days and decays into uranium-233, also through beta decay. If completely fissioned, one pound (0.45 kilograms) of uranium-233 will provide the ...

Isotopes of thorium - Wikipedia

Other articles where Thorium-232 is discussed: fissile material: the fertile materials uranium-238 and thorium-232, respectively. A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor. Thorium-232 and uranium-238 are the only two naturally occurring fertile materials. Any such decay chain is only stopped by the formation of a stable nucleus. This occurs at the fourteenth generation of the uranium 238 family, when lead 206 is finally produced. The two other families, those formed from uranium 235 and thorium 232, end respectively with the creation of lead 207 and lead 208, two other stable isotopes of lead.

Thorium, Chemical Element - reaction, uses, elements ...

The trick is to start with an isotope of thorium, thorium-232. Thorium-232 has a very long half life of 14 billion years. If thorium-232 is bombarded with neutrons, it goes through a series of nuclear changes, first to thorium-233, then to protactinium-233, and finally to uranium-233. The whole process only takes about a month. Jun 19, 2016· Thorium is the bomb -- one reason being, it isn't. This feature is not available right now. Please try again later.

The isotope thorium-228 also occurs in the decay series of thorium-232, i.e. in the chain of nuclear products produced as thorium-232 disintegrates. Most of these are short-lived isotopes and hence more radioactive than thorium-232; they are negligible in mass. A diagram of the decay series follows in the next footnote.
