Presentation transcript:

We’ll go over this example in video form.

We’re asked to name the compound with the formula NH 4 NO 3 Name the compound with the formula NH 4 NO 3

We see that NH 4 NO 3 has 3 elements (click) nitrogen, hydrogen and oxygen. Any ionic compound with more than two elements must contain a polyatomic ion. NH4NO3NH4NO3 3 Elements Name the compound with the formula NH 4 NO 3

So we look on the ion table for polyatomic ions in the formula NH 4 NO 3 and we find there are two polyatomic ions NH 4 NO 3 Name the compound with the formula NH 4 NO 3

NH4 is from the ammonium ion, NH4 plus NH 4 NO 3 Name the compound with the formula NH 4 NO 3

And NO 3 is from the nitrate ion, NO 3 minus NH 4 NO 3 Name the compound with the formula NH 4 NO 3

So NH4NO3 is made up of the ammonium ion and the nitrate ion. Both of these are polyatomic ions, and their names do not change when they form a compound. Name the compound with the formula NH 4 NO 3 ammonium nitrate

So the name is simply ammonium (click) Name the compound with the formula NH 4 NO 3 ammonium nitrate

nitrate Name the compound with the formula NH 4 NO 3 ammonium nitrate

Polyatomic ions have only one possible charge each, so there are never any roman numerals after the names of polyatomic ions. Name the compound with the formula NH 4 NO 3 ammonium nitrate No Roman Numerals

So the final answer is, (click) the name of the compound with the formula NH4NO3 is ammonium nitrate. Name the compound with the formula NH 4 NO 3 ammonium nitrate
