Kris Kross Method! Ca 3 As 2 Ca 2+ As 3-

Which charge ALWAYS comes first? POSITIVE!!!

Which type of element ALWAYS comes first? METAL!!!

K F Ba N Ga O Ca Cl K Si Co I

K 1+ F 1- Ba N Ga O Ca Cl K SiCo I

KF Ba N Ga O Ca Cl K SiCo I

KF Ba 2+ N 3- Ga O Ca Cl K SiCo I

KF Ba 3 N 2 Ga O Ca Cl K SiCo I

KF Ba 3 N 2 Ga 3+ O 2- Ca Cl K SiCo I

For POLYATOMICS it gets a bit more complex Pb 4+ SO 4 2- Pb 2 (SO 4 ) 4 NH 4 1+ PO 4 3- (NH 4 ) 3 PO 4

Naming Ionic Compounds

What do you see? Copy the table into your notes and fill in the question marks with what you think is correct. Formula for Ionic Compound Name for Ionic Compound NaClSodium chloride CaCl 2 Calcium chloride KBrPotassium bromide MgF 2 ??? NaBr???

Naming Ionic Compounds 1)Write name of first element (metal). 2)Second element ends in -ide. 3)Ignore subscripts!

Naming Ionic Compounds Draw a mental line between the ions. Na + Cl -

Naming Ionic Compounds Binary Ionic Compound – an ionic compound composed of two elements

Naming Ionic Compounds ZnO

Naming Ionic Compounds ZnO Zinc Oxide

Naming Ionic Compounds CaCl 2

Naming Ionic Compounds CaCl 2 Calcium Chloride

Naming Ionic Compounds Al 2 O 3

Naming Ionic Compounds Al 2 O 3 Aluminum Oxide

Naming Ionic Compounds Ternary Ionic Compound – an ionic compound with more than 2 elements

Naming Ionic Compounds Ionic Cheat Sheets!

Naming Ionic Compounds Do not lose this…you will need it the rest of your life (in my class).

Naming Ionic Compounds The way you use it…

Naming Ionic Compounds 1) Look up the ions on the cheat sheet and write the words next to them.

Naming Ionic Compounds BaCO 3

Naming Ionic Compounds BaCO 3 Normally the first element is the first piece and the rest is the second piece.

Naming Ionic Compounds BaCO 3 Barium

Naming Ionic Compounds If the first element is +2, where should we find the second? (Remember, charges must balance!)

Naming Ionic Compounds BaCO 3 Barium

Naming Ionic Compounds BaCO 3 Barium Carbonate

Naming Ionic Compounds AlPO 3

Naming Ionic Compounds AlPO 3 Aluminum

Naming Ionic Compounds AlPO 3 Aluminum Phosphite

Naming Ionic Compounds H 3 PO 4

Naming Ionic Compounds H 3 PO 4 Hydrogen

Naming Ionic Compounds H 3 PO 4 Think: H +, we have 3 which means +3, where will PO 4 be?

Naming Ionic Compounds H 3 PO 4 Hydrogen Phosphate

Naming Ionic Compounds FeSO 4

Naming Ionic Compounds FeSO 4 Notice Iron appears in +2 and +3…

Naming Ionic Compounds FeSO 4 Sulfate

Naming Ionic Compounds FeSO 4 Since Sulfate is -2, Fe must be +2

Naming Ionic Compounds FeSO 4 Iron(II) Sulfate

Naming Ionic Compounds FeSO 4 Iron(II) Sulfate or Ferrous Sulfate
