Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), traditional names have also been kept where they are in wide use or of significant historical interests.
Well-known types of reactions that involve inorganic compounds include: ... List of inorganic compounds; Inorganic compounds by element
This table lists only the occurrences in compounds and complexes, not pure elements in their standard state or allotropes. Noble gas +1 Bold values are main oxidation states
Stoichiometric names are the simplest and reflect either the empirical formula or the molecular formula. The ordering of the elements follows the formal electronegativity list for binary compounds and electronegativity list to group the elements into two classes which are then alphabetically sequenced. The proportions are specified by di-, tri ...
Oxidation numbers are assigned to elements in a molecule such that the overall sum is zero in a neutral molecule. The number indicates the degree of oxidation of each element caused by molecular bonding. In ionic compounds, the oxidation numbers are the same as the element's ionic charge.

There are a number of exceptions and special cases that violate the above rules. Sometimes the prefix is left off the initial atom: I 2 O 5 is known as iodine pentaoxide, but it should be called diiodine pentaoxide. N 2 O 3 is called nitrogen sesquioxide (sesqui-means 1 + 1 ⁄ 2). The main oxide of phosphorus is called phosphorus pentaoxide.
An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.
