What element is thorium on the periodic table?
90
Thorium/Atomic number
Thorium (Th), radioactive chemical element of the actinoid series of the periodic table, atomic number 90; it is a useful nuclear reactor fuel. Thorium was discovered (1828) by Swedish chemist Jöns Jacob Berzelius. It is silvery white but turns gray or black on exposure to air.
Is thorium on the periodic table?
Today, its radioactivity seems logical as when we look at the periodic table, we find thorium, element 90, just after actinium in the last row of the periodic table known as the actinides, comprising of famous radioactive elements such as uranium and plutonium.
Where is uranium on the periodic table?
92nd
Uranium: Uranium is the 92nd element on the periodic table and is widely regarded to be the last naturally occurring element in abundance. It’s a dense metal that is weakly radioactive compared to other radioactive metals.
What is the safest element?
Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90….
| Thorium | |
|---|---|
| Appearance | silvery, often with black tarnish |
| Standard atomic weight Ar, std(Th) | 232.0377(4) |

Where can you find thorium on the periodic table?
Thorium is found in small amounts in most rocks and soils. Soil commonly contains an average of around 6 parts per million (ppm) of thorium. Thorium occurs in several minerals including thorite (ThSiO 4 ), thorianite (ThO 2 + UO 2) and monazite. Thorianite is a rare mineral and may contain up to about 12% thorium oxide.
What kind of energy can thorium be used for?
Thorium can be used as a source of nuclear power. It is about three times as abundant as uranium and about as abundant as lead, and there is probably more energy available from thorium than from both uranium and fossil fuels.
What are the physical properties of thorium oxide?
The physical properties of thorium are greatly influenced by the degree of contamination with the oxide. The purest specimens often contain several tenths of a percent of the oxide. High-purity thorium has been made. Pure thorium is soft, very ductile, and can be cold-rolled, swaged, and drawn.
What is the atomic number of thorium 90?
Thorium is a chemical element with symbol Th and atomic number 90. Classified as a n actinide, Thorium is a solid at room temperature. ZSLUVFAKFWKJRC-UHFFFAOYSA-N
