The density of thorium is 11,724 g/cm3.
Thorium has no biological role. Thorium is a heavy, radioactive metal which is not used in the human body.
uranium,thorium,actinium and neptunium
Thorium is not used in the human body. While thorium is a naturally occurring element, it is not essential for human health and can be harmful if ingested or inhaled, as it is radioactive. It is primarily used in industrial and energy applications.
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 is typically found only in dark-colored heavy-mineral sands. Mineral bearing sand is classified by specific gravity as either light or heavy, with heavy mineral sands having a specific gravity of greater than 2.9. Many of the heavy mineral sands are dark colored and include ilmenite, rutile, magnetite, sphene, and garnet. Thorium is found primarily in the heavy mineral. monazite, which is ofter yellowish-brown or greenish- brown. A minor amount of thorium may also be in the heavy mineral, zircon, which is often white of yellowish in color. Because monazite and zircon are heavy minerals and are generally less abundant than ilmenite in a deposit, they are typically found in the zones of dark or black colored minerals. It is possible for thorium-bearing minerals to be distributed throughout a light-colored sand.
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.
Thorium and fluorine Thorium trifluoride - ThF3 Thorium tetrafluoride - ThF4
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
