Cations + 5:22 AM

anions e g a t i v r e 5:22 AM

- composed of two or more nonmetals eg. CF4 C6H12O6 P4 Types of Compounds Molecular Compounds - composed of two or more nonmetals eg. CF4 C6H12O6 P4 5:22 AM

Types of Compounds NEW STUFF!! Acids - acids are hydrogen compounds that are dissolved in water eg. HF(aq) H2SO4(aq) aqueous 5:22 AM

Naming & Formulas A. Molecular Compounds common formulas PS: HOFBrINCl prefixes indicate the number of each atom in binary molecular compounds last element ends in - ide 5:22 AM

Naming & Formulas eg. N3H5 disulfur octahydride 5:22 AM

Naming & Formulas B. Ionic Compounds - simple ions - multivalent metals - polyatomic ions - hydrates 5:22 AM

BeF2 Naming & Formulas Simple Ions (only one possible charge) - Cross Over Method - reduce to lowest terms eg. calcium chloride sodium nitride magnesium sulfide K2O BeF2 5:22 AM

‘CrossOver’ Method magnesium ion nitride ion 3- 2+ Mg N Mg3N2 5:22 AM

Cancel Charges (LCM) Mg N 2+ 3- x 2 6- x 3 6+ Mg3N2 5:22 AM

Naming & Formulas Multivalent Ions - Stock system (Roman numerals) - Classical system -ic indicates bigger charge -ous indicates smaller charge - reduce to lowest terms 5:22 AM

Naming & Formulas eg. lead (II) chloride lead (IV) chloride NiCl3 lead (IV) nitride lead (IV) sulfide NiCl3 CuO Cu2O 5:22 AM

Naming & Formulas Polyatomic Ions - a group of atoms with a charge - cross over method / lowest terms - BRACKETS eg. calcium hydroxide ammonium sulfate PbSO4 Sn3(PO4)4 5:22 AM

Naming & Formulas Hydrates - water mixed in with the ions - heating removes the water to make an anhydrous (dry) compound - use prefixes to indicate ratio of water to ions eg. CuSO4• 5 H2O copper (II) sulfate pentahydrate lithium chloride dihydrate 5:22 AM

Naming & Formulas Acids - acids form when hydrogen compounds are dissolved in water - the subscript (aq) is used to indicate aqueous or dissolved in water - 3 rules for naming acids 5:22 AM

Naming & Formulas Ionic name  Acid name hydrogen ___ide  hydro___ic acid hydrogen ___ate  ______ic acid hydrogen ___ite  ______ous acid 5:22 AM

Naming & Formulas Writing Acid Names - write the ionic name for the hydrogen compound - apply the correct rule for the acid name eg. HCl(aq) hydrogen chloride  hydrochloric acid 5:22 AM

Naming & Formulas eg. HCl(aq) hydrogen chloride  hydrochloric acid eg. HClO3(aq) hydrogen chlorate  chloric acid eg. HClO2(aq) hydrogen chlorite  chlorous acid 5:22 AM

 hydrogen bromate  H+ BrO3-  HBrO3(aq) Naming & Formulas Writing Acid Formulas - use the correct rule to write the ionic name - use ion charges to write the formula eg. bromic acid  hydrogen bromate  H+ BrO3-  HBrO3(aq) 5:22 AM

 hydrogen bromide  H+ Br -  HBr(aq) Naming & Formulas hydrobromic acid  hydrogen bromide  H+ Br -  HBr(aq) 5:22 AM
