Naming compound

organic compound

contain carbon and hydrogen

inorganic compound

dont contain hydrogen and carbon

naming cations from metal ions

have the same name as the metal + ion

naming metal with different charges

use roman numeral to indicate how many ions

naming cations fro nonmetal atoms

end in -ium

monatomic anions

end in -ide

naming monatomic anions expections (polyatomic anions that end in -ide)

OH^-(hydroxide ions), CN^-(cyanide ions), O₂^2-(peroxide ions)

Oxyanions (anions contain oxygen)

• end in -ate or -ite

• -ate is more common or more oxygen atoms -ide used for fewer oxygen atoms than -ate

• per- indicates more O than -ate Hypo- indicates less O than -ide

CO₃^2-

carbonate ion

NO₃^-

Nitrate ion

PO₃ ^3-

Phospate ions

SO₄ ^2-

Sulfate ion

CIO₄^-

Perchlorate ion

Naming anions with added H⁺ to oxyanions

hydrogen or dihydrogen as prefix

naming inorganic acid: acid from -ide anions

add prefix hydro- and change -ide to -ic followed by acid

naming inorganic acid: acids from -ate ions

-ate to -ic follwed by acid

naming inorganic acid: acid from -ite anions

-ite to -ous followed by acid
