- thorite: silicates group
- monazite: phosphates group
Uranium and thorium are in the actinoids family.

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.

Zinc is a metal element and is not classified under a specific mineral group. It is commonly found in nature as the mineral sphalerite, which is a zinc sulfide.
