Uranium and thorium are in the actinoids family.
thorium
Thorium is an inner transition element, which means it is a metal.

Thorium is mainly found in India.
Thorium is a member of the actinoids family and is placed in period 7.
Thorium is extracted from minerals as monazite, thorianite, thorite, the mineral is grounded, dissolved in nitric acid, thorium is extracted with tributylphosphate. Also other methods exist.Pure thorium is obtained from ThO2 by a calciothermic process, from ThI2 by thermal decomposition or from ThF4 by electrolysis.
Like all metals except for mercury thorium's standard state is solid.
Kerala, a state in southern India, is known to have the world's largest deposit of thorium. Its monazite sands contain significant amounts of thorium, a valuable radioactive mineral used in nuclear technology.
Yes, thorium is a naturally occurring radioactive element that is often found in minerals such as thorite, monazite, and thorianite. It is used in various industrial applications, including nuclear reactors and gas lantern mantles.

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.
