Binary Covalent Nomenclature

Rules of Binary Covalent Nomenclature

The naming system is for compounds composed of two nonmetallic elements.
The first element keeps its name
The first element gets a prefix if it has a subscript in the formula
The second element gets the –ide suffix (ending)
The second element ALWAYS gets a prefix

prefix	number indicated
mono-	1
di-	2
tri-	3
tetra-	4
penta-	5
hexa-	6
hepta-	7
octa-	8
nona-	9
deca-	10
