2 Naming Compounds Graphic Organizer and Practice Problems

3 Naming Compounds Check 1st Element Ionic -if it’s a metal -if it’s a H -if you have C and H -if it’s a nonmetal Split into ions Anion- -ide or polyatomic Cation- same as element Acid -ide(anion), hydro____ic acid -ite(anion), ____ous acid -ate(anion), ____ic acid Organic Molecular *Name elements from left to right using the periodic table *use prefixes to tell how many *end in -ide Put together ions so net charge is 0 # of H’s match the charge of the anion Check charge for transition metals

4 Practice Part 1 FeS First element is a metal, so it is ionic Cation would be iron Anion would be sulfide Iron (II) sulfide NCl 3 First element is a nonmetal, so it is molecular Nitrogen trichloride

5 Practice Part 1 (cont.) CoSO 4 First element is a metal Cobalt (II) Sulfate H 3 PO 3 First element is H, so it is an acid Normally would end in -ite, so should be an -ous acid Phosphorous acid

6 Practice Part 2 potassium sulfide First element is a metal, so it is ionic Potassium ion is K + Sulfide ion is S 2- To balance charges it should be K 2 S Hydrobromic acid Its is a hydro __ic acid, so it should end with -ide Bromide has a -1 charge HBr

7 Practice Part 2 (cont.) Tin (IV) chloride Starts with a metal, so it is ionic (IV) means tin has a +4 charge Chloride has a -1 charge SnCl 4 Dinitrogen pentoxide Uses prefixes so it is molecular Di means it has 2 nitrogens Pent means it has 5 oxygens N 2 O 5
