Presentation Transcript

  1. Naming Compounds Ionic and Covalent

  2. First thing first… • Determine if the compound is Ionic or Covalent. • Ionic = Metal + Nonmetal • Covalent = Nonmetal + Nonmetal

  3. Nonmetals Metals Metal vs Nonmetal

  4. Nonmetals Metals Metal vs Nonmetal

  5. Metal vs Nonmetal Nonmetals Metalloids Metals

  6. Ionic: Binary (2 elements) • Positive ion + Negative ion • Change ending to “ide”

  7. Ionic Naming • Subscripts have no affect on the name. • Example: • NaCl = Sodium Chloride • CaCl2 = Calcium Chloride

  8. Transition Metals • Roman Numerals are used to indicate the CHARGE of transition metals. • 1 I • 2 II • III • 4 IV • V • VI • VII • VIII • IX • X

  9. Transition Metal Example Charge of Nickel (+3) Nickel (III) Sulfide Charge of Sulfur (-2) +3 -2 Ni2S3

  10. Polyatomic ions • An ion containing more than one atom.

  11. Polyatomic ion Families

  12. Common Polyatomic Ions • NH4+ ammonium • CN- cyanide • OH- hydroxide • NO3- nitrate • NO2- nitrite • SO4-2 sulfate • SO3-2 sulfite • PO4-3 phosphate • ClO3- chlorate • MnO4- permanganate • CO3- carbonate

  13. Memorizing Polyatomics OH NO SO CO PO -1 -1 -2 -2 -3 3 4 3 4 hydroxide nitrate sulfate carbonate phosphate

  14. Using polyatomics +2 +3 Magnesium Phosphate Mg PO4 Mg3(PO4)2

  15. What to remember about ionic compounds • End in “ide” • Transition metals • Roman Numeral indicates charge • Polyatomic ions

  16. Try a few Ionic Compounds • K3N __________________ • CuOH __________________ • FePO4 __________________ • MgO __________________

  17. Try it the other way • Vanadium (III) sulfide _______ • Manganese (II) phosphate _______ • Sodium oxide_______ • Lithium Fluroide _______

  18. Covalent Naming • Know your prefixes 1 Mono 2 Di 3 Tri 4 Tetra 5 Penta 6 Hexa 7 Hepta 8 Octa 9 Nona 10 Deca

  19. Use the prefixes • The prefix indicates the number of atoms of the element • Change the ending of the second compound to “ide” Ends in “ide” diphosphorous trioxide 2 Phosphorous atoms 3 Oxygen atoms

  20. Use the prefixes • If the first element is singular do not use the mono prefix. Ends in “ide” Carbon dioxide 1 Carbon atoms 2 Oxygen atoms

  21. Use the prefixes • If the second element is singular you must use the mono prefix. Ends in “ide” Carbon monoxide 1 Carbon atoms 1 Oxygen atom

  22. Try a few Covalent Compounds • NF3 ___________________________ • Si2Br6 ___________________________ • N2O3 ___________________________ • ClO2 ___________________________ • CF4 ___________________________

  23. Try it the other way now • Hexaboron Silicide ______________ • Dihydrogen monoxide ______________ • Iodine pentafluoride ______________ • Phorsphorous triiodide ______________ • Carbon tetrachloride ______________

  24. YAY! You are now an expert at naming compounds 
