What is the common compound of thorium?
Common compounds of thorium: thorium dioxide, thorium trifluoride, thorium tetrafluoride, thorium tetrachloride, thorium triiodide, thorium diiodide, thorium tetraiodide, thorium nitrate, thorium oxalate, thorium carbide, thorium sulfides, thorium nitride, thorium oxinate, etc.
How did Jakob berzelius discover thorium?
Jakob Berzelius did not discover thorium; it was discovered by the Swedish chemist Jöns Jakob Berzelius in 1828. Berzelius isolated thorium by heating a sample of the mineral thorite with potassium hydroxide and then treating it with hydrofluoric acid.
What are the advantages and disadvantages of thorium?
Some thorium uses: - fertile material (as ThO2) in nuclear power reactors; is a precursor of the fissile isotope 233U. - thorium dioxide can be used as refractory material for crucibles, tubes, rods, etc. - thorium tetrafluoride (ThF4) is used as anti-reflection coating in optics. - gas mantles (as ThO2) - alloying metal for some aviation components (magnesium-thorium alloy, magnesium-zinc-thorium); also for welding alloys wolfram-thorium - additive (as ThO2) in wolfram filaments - to stop crystalline growth of W and to increase time of use of light bulbs - catalyst in organic chemistry (as ThO2) - additive for special glass (as ThO2) - additive in filaments (as ThO2) of magnetron tubes - reagent in chemistry laboratories (as thorium nitrate) - etc. Disadvantages of thorium: 1. Thorium is a possible polluting agent of the natural environment. 2. Thorium is a radioactive chemical element. 3. Thorium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated.
What chemicals are in thorium fluoride?
Thorium and fluorine Thorium trifluoride - ThF3 Thorium tetrafluoride - ThF4
Common commpouds of thorium?
Hazards and Health Considerations: Thorium presents both a toxic and radiological hazard. Toxicologically, it causes heavy metal poisoning similar to lead or the uranium isotopes. Biologically, thorium accumulates in the skeletal system where it has a biological half-life of 200 years, the same as plutonium. An M 17 protective mask and standard anti-contamination clothing will adequately protect against thorium.
Is thorium homogeneous?
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
What is the English name of an thorium?
Also thorium.
What is the symbol for the element thorium?
The chemical symbol of thorium is Th.
How many neutrons are in thorium?
232Th has 142 neutrons and 90 protons and electrons.
Do I require a licence to buy thorium and to make a domestic steam generator fuelled by thorium?
Of course, thorium is a controlled material and working with thorium is not a joke for home.
What is thorium family name?
Thorium (Th) is a member of the actinoids family.
What is thorium smell like?
Thorium itself is odorless in its natural state. However, thorium compounds may have a slight metallic or musty odor. It is always important to handle thorium with proper precautions due to its radioactive properties.
