Thorium(IV) sulfide
Encyclopedia
Thorium sulfide (Th
S2
) is an inorganic chemical compound
composed of one thorium
atom ionically bonded
to two atoms of sulfur
. It is dark brown and has a melting point of 1905°C. The thorium in the compopund is unstable and decays by emitting alpha radiation. ThS2 atopts the same lattice structure as TiO2.

Sulfur
Sulfur or sulphur is the chemical element with atomic number 16. In the periodic table it is represented by the symbol S. It is an abundant, multivalent non-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8. Elemental sulfur is a bright yellow...

Chemical compound
A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together...

Ionic bond
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. Pure ionic bonding cannot exist: all ionic compounds have some...
