Unformatted text preview: Per = “more” Changing # Oxygen Hypo=“less” (No per- or hypo- on exam 1) Realize that the "-ates" are blue, if you know those you'll notice the "-ites" are one less. 6 9/10/2013 O_ N OO Practice with Polyatomic Anions Mn(NO3)3 Manganese (__) nitrate CaSO4 ___________________ Zn3(PO4)2 __________________ O_ N OO M?+ O_ N OO perchlorate = ClO4Fe(ClO4)2 Iron ( __ ) perchlorate NH4C2H3O2 _________________ Notice this looks out of order for the atoms. Why is it correct? Nomenclature: Molecular Compound Molecular Compound – two or more non-metals (no metals) Prefix + name element 1 Prefix + base name element 2 + ide Memorize Example: N2O4 Dinitrogen tetroxide these No “mono-” Prefixes on first Mono1 Carbon _____oxide CO element Di2 Carbon _______sulfide CS2 Tri3 Tetra4 N2O ___nitrogen _______oxide Penta5 PCl5 Hexa6 ___phosphorus ______chloride Hepta7 Octa8 Prefixes are necessary since for nonmetals the charge is less obvious. 1: Ionic or molecular? 2: Does it need the roman numeral charge? Type 1 or 2? Nomenclature Examples Chemical formula ⇔ Formula Mass Relationships Formula Mass – Sum atomic masses of all atoms in formula. (masses as amu in periodic table) Mg(O...
