Naming Binary Inorganic Compounds:
Naming Binary Inorganic Compounds Binary compounds – compounds containing only two elements To name a binary compound: Write down the name of the element with the positive oxidation number Add the name of the element with the negative oxidation number Change the ending of the “negative element” to -ide
Name the following…:
Name the following… BaS CaO ZnF 2 AlCl 3 H 2 O Barium sulfide Calcium oxide Zinc fluoride Aluminum chloride Hydrogen oxide (water) Pause the Presentation and complete the remaining examples
Elements With More Than One Oxidation Number:
Elements With More Than One Oxidation Number We need to specify which oxidation state we’re talking about for some elements (i.e. – tin, iron, copper) Stock system (uses Roman numerals) Indicate positive ion charge - ous vs. – ic system “ ous ” for lower oxidation number “ ic for higher oxidation number
Naming Compounds with Polyatomic Ions:
Naming Compounds with Polyatomic Ions Very similar to naming binary compounds The ending of the polyatomic ion is not changed (ex. Aluminum phosphate – AlPO 4 )
