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.

Thorium: natural chemical element, metal, solid, radioactive, actinoids family, period 7, atomic number 90, used in breeder reactors, etc.
A transition element of f-block Thorium has 90 electrons in natural state, it is a Radioactive element.
The atomic number of thorium, Th, is 90 and it is an inner transition element in the Actinide series. The Actinide series is the second of the two series shown by themselves. It starts Actinium, Thorium, Protactinium, and Uranium, so Thorium is the second element in the Actinide series.
Thorium 230 has 90 protons and 140 neutrons - the difference is 50.
Thorium has 90 electrons.
Thorium is a metal element. There are 90 electrons in a single atom.
Element 90 is thorium.
Thorium (Th).
Thorium has 90 electrons.
Th, element 90, spelled thorium, is an actinide and has been used as a nuclear fuel (see Wikipedia.)
Thorium , aftet the Norse God , Thor. Thor is the Norse God of thunder. Thorium is found in the Periodic Table at No. 90 . ( An Actinide element).
