Nomenclature and formulas of compounds

 What a compound is and how structure affects properties of compounds  Discuss differences and similarities between ionic, covalent, and metallic bonds.  Name and write formulas for ionic and covalent compounds.  Differentiate between alkane, alkene, and alcohol.  Recognize polymers and relate them to your life.

 Mixture  Compound  Same chemical formula  Chemical bond  Chemical structure  Bond length  Bond angle

 Ball and stick  Space filling  Structural formula

 Ionic  Metal and nonmetal  Covalent  nonmentals  Metallic  metals

 Gain and lose electrons  Metal and nonmetal  Conduct electricity when dissolved in water

 2 nonmetals  Sharing of electrons  Polar  Nonpolar  Polyatomic ions

 Sea of electrons

 Name the cation first and the anion second.  Monatomic cations use the element name.  Monatomic anions take their name from the root of the element name plus the suffix –ide.  If the compound contains a polyatomic in, simply name the ion.

 Li 2 O  BeCl 2  NaCl  MgBr 2  K 2 (SO 4 )  (NH 4 ) 3 PO 4

 Lithium oxide  Beryllium chloride  Magnesium bromide  Potassium sulfate  Ammonium phospate

 To figure out the charge of the transition metal  Multiply the number of anions by the charge  The cations overall charge will be equal to but opposite  Divide the overall charge by the amount of cations  This gives you the charge of each cation  Put this number in roman numerals and in parenthesis

 TiN  FeO  Fe 2 O 3

 As 2 O 5  SiI 4  P 4 S 3  PCl 3  P 4 O 10

 Diarsenic pentoxide  Silicion tetroxide  Tetraphosphorus trisulfide  Phosphorous trichloride  Tetraphosphorous decoxide

 C based compounds  Alkane  End in –ane  Single bonded carbons  Methane  Ethane  Propane  Alkene  End in –ene  Double bonded  Ethene  propene

 Alkyne  Triple bonded C  Propyne  Butyne  Alcohol  End in –ol  Have an –OH group on them  Methanol  Ethanol  Propanol

 Polymers- large organic molecule made of many smaller bonded units  Biochemical Compounds- organic compound that has an important role in living things  carbohydrate  proteins  amino acid
