Where is thorium located on the periodic table?
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.

What is americium element family?
Americium belongs to the actinide element family, which is a group of radioactive elements found in the actinide series of the periodic table. Actinides are characterized by their high atomic numbers and radioactivity. Members of this family include uranium, plutonium, and thorium.
Is actinide considered a synthetic element?
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
