Thorium 230 is an alpha emitter with half life 75,380 years. Therefore it is dangerous if ingested. Alpha particles don't penetrate the skin, so it would not be dangerous to handle carefully, but if ingested alpha particles can damage internal organs. Thorium 234 is a beta emitter with half life 24.1 days. So 230 is the more dangerous.
the difference between plasma and the other states of matter is that,plasma is an ionized gas.
No difference one is just fancier than the other
See the question "What is QPSK". If you want the difference between QPSK and some other modulation system, you'll need to name the other one.
One has a space in between, the other doesn't
can not be used with each other
One is an idea and the other a big dangerous animal.
Thorium can be separated from other elements by solvent extraction with tributylphosphate.
To obtain pure thorium metal it is necessary to separate thorium from other elements.
Thorium as a metal is obtained by a calciothermic process from thorium dioxide. Other methods are: electrolysis of thorium tetrafluoride and thermal decomposition of thorium tetraiodide (Van Arkel-de Boer process).
Thorium is a tetravalent element. Thorium react slowly with water; thorium can react with concentrated nitric acid and hydrogen chloride. Thorium can react with the majority of other chemical elements. The Pauling electronegativity of thorium is 1,3.
Important minerals of thorium are: monazite, thorite, thorianite, allanite.
Thorium can react with the majority of the other nonmetals.
police dogs are trained to sniff out drugs and other dangerous stuff such as like bombs.
Thorium B is 212Pb: radioactive isotope of lead. Thorium D is 208Pb: stable isotope of lead.
Thorium can be strip mined and it could be deep mined. It is be produced as a byproduct of the production of rare earth elements, and since the current production as a byproduct far exceeds the demand, it is not usually mined.
Th(NO3)4 + 2 H2C2O4-----------Th(C2O4)2 + 4 HNO3 Thorium oxalate is a white powder, toxic, used in the analytical chemistry of thorium and in the technology of thorium separation from other elements.
Thorium can react with many other elements: oxygen, silicon, carbon, nitrogen, sulfur, selenium, halogens, etc.
