Nomenclature Naming compounds

Ionic Compounds Cation (metal): The name of the element stays the same Anion (non-metal): Change the ending of the element to –ide Polyatomic: go with the given name

Covalent Compounds The more positive atom is written first (furthest to the left and to the bottom of the periodic table) The more negative atom is second and change the ending of the element’s name to -ide Count how many atoms of each element in the formula Need to know the prefixes Each prefix tells how many of each atom there are.

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