Thorium: natural chemical element, metal, solid, radioactive, actinoids family, period 7, atomic number 90, used in breeder reactors, etc.
Thorium is an inner transition element, which means it is a metal.
Thorium is a tetravalent element (4+).
Thorium can be used as fertile material (as ThO2) in nuclear power reactors; is a precursor of the fissile isotope 233U. This type of reactor is called a breeder: the reactor produce more fissile material than it consumes. It is a very strange and important characteristic.
When uranium radiates alpha particles, it transforms into thorium. Thorium is a radioactive element that is produced as a result of the decay of uranium through alpha emission.
Thorium is generally known by its chemical name "Thorium." However, it may also be referred to as "Th" on the periodic table.

The chemical symbol of thorium is Th.
The chemical symbol for thorium is Th.
Thorium is a natural chemical element.
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
Tall is not an adequate term for a chemical element.
Thorium is a natural chemical element; chemical elements were formed by stellar nucleosynthesis at the beginning of the universe.
Thorium is not a radiation but a chemical element, metal, natural and radioactive.
The name of the chemical element thorium is derived from the name of the Scandinavian god Thor.
The element named after Thor is thorium, with the chemical symbol Th. It is a radioactive element that is commonly used in nuclear reactors and various other applications.
Thorium is a name derived from the Scandinavian deity Thor; the symbol of the chemical element is Th.
Thorium is a natural chemical element, a radioactive metal.
