  1. Bell ringer- Name or generate formulas for the following: GeS2 Scandium nitride CaO Vanadium (V) ferrocyanide

  2. Covalent Bonds Nomenclature

  3. Covalents watch until 11:25 mark

  4. BrightStormCovalent naming

  5. Identify the following as ionic or covalent- • Sodium chloride • Cl2 • Dihydrogen monoxide • MgCl2 • Germanium Carbide • CH4 Bellringer

  6. Steps to naming Covalents • Id metal, nonmetal (must not have a metal) • Write out element names, drop • the ending off second one and replace • with –ide • Count how many of each element • you have. • 4. Place the prefix that corresponds to the number in front of the element name.

  7. Special notes- • Don’t ever simplify covalents • When using tetra or penta with an oxide drop the –a and just use -tetr or –pent • When using mono- with an oxide drop the –o and just use mon- • Don’t use mono- on the first word

  8. List of prefixes-

  9. Dinitrogen tetrafluoride Silicon tetrachloride Chlorine trifluoride Silicon dioxide

  10. Covalent naming

  11. Steps to writing covalent formulas • Id metal, nonmetal (must not have a metal) • Write out symbols. • Read prefix, place corresponding number in the subscript position. If it is a mono-, leave blank don’t write the one in the subscript position. • Don’t simplify!

  12. Carbon dioxide CO2 Phosphorous triiodide PI3 Sulfur dichloride SCl2 Nitrogen trifluoride NF3 Dioxygen difluoride O2F2

  13. Now it’s your turn. On the Nomenclature Worksheet, complete all problems. Mixed Ionic/Covalent Problems is for homework due Friday! Phosphorus = P4 Oxygen = O2 CH4 = methane Nitrogen = N2
