Nomenclature is a set or system of names. The nomenclature that we use in chemistry is based on the IUPAC (International Union of Pure and Applied Chemists) . The following simplified rules can be used to name the most of inorganic compounds.
Naming Simple Covalent Compounds:
Binary Covalent Compounds (only 2 elements form the compound)
Covalent compounds use prefixes in both names
Format: PREFIXelement1 PREFIXelement2IDE
Mono (never used in the first name)
Di
Tri
Tetra
Penta
Hexa
Hepta
Octa
Nona
Deca
Name the non-metal furthest to the left or to the bottom on the periodic table by its elemental name with the prefix if different than 1
Name the second non-metal (the more electronegative) by its elemental name with the prefix and the suffix “ide” at the end.
The first non-metal will not change the name, the second non-metal will get the suffix “IDE”
