Prefixes and Suffixes...

Numeric prefixes (mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca)

These are ONLY used for the following:

-Metal-containing acids and acid ions: the prefix ONLY goes on the hydrogen (mono is dropped)

Examples:

H₂AsO₄^- = dihydrogen arsenate ion

HAsO₄^2- = hydrogen arsenate ion

NaH₂PO₄ = sodium dihydrogen phosphate

NaHSeO₃ = sodium hydrogen selenite

Other Examples:

H₂AsO₄^-, H₂PO₄^-, HAsO₄^2-, HCO₃^-, HPO₄^2-, HSeO₃^-, HSeO₄^-, HSO₃^-, HSO₄^-, HTeO₃^-, HTeO₄^-, Na₂HAsO₄, Na₂HPO₄, NaH₂AsO₄, NaH₂PO₄, NaHCO₃, NaHSeO₃, NaHSeO₄, NaHSO₃, NaHSO₄, NaHTeO₃, NaHTeO₄, CaHAsO₄, CaHPO₄

-Nonmetal/nonmetal binary compounds that are NOT acids: the prefix goes on both first and second element (mono on the first element is dropped).

Examples:

CBr₄ = carbon tetrabromide

TeO₃ = tellurium trioxide

S₂F₆ = disulfur hexafluoride

Other Examples:

CBr₄, CCl₄, Cl₂O₇, ClO₂, CO, CO₂, ICl, N₂O, N₂O₄, N₂O₅, P₂O₃, P₂S₅, P₄O₁₀, PBr₅, PCl₃, S₂F₆, SeO₂, SF₆, SiS₂, SO₂, SO₃, TeO₃
