1. We’ll go over the given example in video form. First of all, we’ll just mention the basic rules for naming a compound that contains a polyatomic ion.

2. The first rule is, the name of a polyatomic ion does not change in any way when it is used in a compound name. Its name is the same in a compound as it is on an ion table. Rules for Naming Compounds with Polyatomic Ions 1.The name of a polyatomic ion does not change when it is used in a compound name. 2.Single elements follow the same naming rules as they do in other compounds.

3. The second rule is, single elements that are not in polyatomic ions, follow the same rules as they do in other compounds. Rules for Naming Compounds with Polyatomic Ions 1.The name of a polyatomic ion does not change when it is used in a compound name. 2.Single elements follow the same naming rules as they do in other compounds.

4. Here is an example, we’re asked to name the compound NaHCO 3. Name the compound with the formula NaHCO 3

5. We see that NaHCO3 has 4 elements (click) sodium, hydrogen, carbon, and oxygen. Therefore, it must contain a polyatomic ion. NaHCO 3 4 Elements Name the compound with the formula NaHCO 3

6. NaHCO 3 Looking on the table, we see that Na in the formula, Name the compound with the formula NaHCO 3

7. NaHCO 3 Is from the single ion sodium, Na plus. Sodium has only one possible charge, so a roman numeral is not included in the name of this compound Name the compound with the formula NaHCO 3

8. NaHCO 3 We see that the remainder of the formula is HCO3. Name the compound with the formula NaHCO 3

9. NaHCO 3 Which is a polyatomic ion called the hydrogen carbonate, or bicarbonate ion. Name the compound with the formula NaHCO 3

10. Na is the metal sodium NaHCO 3 sodium bicarbonate Name the compound with the formula NaHCO 3

11. Sodium has only one possible charge (click) so there is no roman numeral after sodium in the name NaHCO 3 sodium bicarbonate Name the compound with the formula NaHCO 3 Sodium has only one possible charge so there is no roman numeral after sodium in the name

12. The formula ends with the polyatomic ion HCO3, (click) which is called either hydrogen carbonate, sodium hydrogen carbonate Name the compound with the formula NaHCO 3 NaHCO 3

13. Or bicarbonate sodium bicarbonate Name the compound with the formula NaHCO 3 NaHCO 3

14. So the name of this compound can be either sodium hydrogen carbonate sodium bicarbonate Name the compound with the formula NaHCO 3 NaHCO 3 sodium hydrogen carbonate or

15. Or sodium bicarbonate. sodium bicarbonate Name the compound with the formula NaHCO 3 NaHCO 3 sodium hydrogen carbonate or

16. Remember the rule is, polyatomic ions do not change their name in any way when they form compounds, so hydrogen carbonate and bicarbonate do not change. sodium bicarbonate Name the compound with the formula NaHCO 3 NaHCO 3 sodium hydrogen carbonate Polyatomic ions do not change their name.

17. So the final answer is: the name of this compound is either (click) sodium hydrogen carbonate sodium bicarbonate Name the compound with the formula NaHCO 3 sodium hydrogen carbonate

18. Or sodium bicarbonate. Both names are acceptable. sodium bicarbonate Name the compound with the formula NaHCO 3 sodium hydrogen carbonate
