Presentation Transcript

  1. Nomenclature Naming chemical compounds

  2. Flow Chart to follow

  3. Prefixes 1 mono 7 hepta 2 di 8 octa 3 tri 9 nona 4 tetra 10 deca 5 penta 6 hexa 12 dodeca

  4. Naming compounds CaCl2 Cr(NO3)3 AlPO4 CuCO3 C2S4 NO2 Fe3N2 Na3P

  5. Determining Formulas from Names

  6. How do charges help you decide subscripts? Look up the charges for each element (or polyatomic ion). Determine the least common multiple between the two charges. The factor each charge needs to be multiplied by to give the least common multiple will be the subscript for that element.

  7. Finding Formulas copper(II)phosphate aluminum nitrate calcium hydroxide iron(III)chromate carbon disulfide dibromine monoxide barium arsenate disilicon tetrachloride

  8. Ionic vs. Covalent Ionic compounds result from an exchange of electrons. When you have a metal bonding to a nonmetal they will exchange electrons. Covalent compounds result from sharing electrons. When you have a nonmetal bonding to a nonmetal they will share electrons.

  9. Ionic or Covalent? BaCl2 Cr(NO3)6 FePO4 CuSO3 Si2S4 N2O3 Al3N2 K3P
