The concentration of thorium in the Earth crust is cca. 6 ppm.
Thorium don't smell.
Thorium-232 is appearing in the thorium series.
Thorium is an inner transition element, which means it is a metal.
No, a single name - thorium (Th).
Thorium is a solid metal.
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.
The only common thorium oxide formula is ThO2.
The common minerals of thorium are: monazite, thorianite, thorite.
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.
Thorium carbide is a systematic unique name in chemistry.
Sulfur is of course more common.
Thorium, with the chemical symbol Th, is the chemical element with the atomic number 90.
Thorium and fluorine Thorium trifluoride - ThF3 Thorium tetrafluoride - ThF4
+4 is the most common and the most stable oxidation number
Thorium don't smell.
Thorium (Th).
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
