1 Unit 4: Nomenclature VHS Chemistry

2 Monday, November 27 OBJECTIVE I will identify ionic compounds and name and write formulas for binary ionic compounds. WARM UP Gather the papers from the front. Then discuss the following: What happens when ions form? What is a cation? What is an anion? Be prepared to share your answers with the class.

3 Cations & Anions

4 Metals & non-metals

5

6 Questions for Model One
Identify three elements that form only one cation Identify three elements that form only one anion Identify three elements that form more than one cation In what region of the periodic table are these “multiple ion” elements typically located?

7 Using the model Consider the ions of Potassium and Sulfur. Write chemical formulas for all possible ionic compound using these ions – using the SIMPLEST ratio of potassium to sulfur. Keep in mind: the sum of the charges in an ionic compound must equal ZERO

8 Using the model Consider the ions of iron and sulfur. Write chemical formulas for all possible ionic compounds involving these ions, using the simplest ratios of iron to sulfur. Keep in mind: the sum of the charges in an ionic compound MUST equal zero

10 Circle the symbol for the metal in each of the compounds in Model 2
Model two questions Circle the symbol for the metal in each of the compounds in Model 2 Which element comes first in the name AND formula for the compounds in metal two – the metal or the nonmetal?

11 Why is a ratio of 3 to 2 necessary for the zinc phosphide compound?
Using both models In the compound zinc phosphide, what is the charge on the zinc ion? How do you know? In the compound zinc phosphide, what is the charge on the phosphide ion? How do you know? Why is a ratio of 3 to 2 necessary for the zinc phosphide compound?

12 Key question Explain why you don’t need to specify the number of ions in the compound when you are naming ionic substances like those in Model 2. For instance, why don’t I have to say “Zinc three Phosphide two”?

13 What’s up with the names?
How do we change the non- metal names to show that they have ionized?

14 Name the following ionic compounds using what you have learned so far:
Check in Name the following ionic compounds using what you have learned so far: Li2O MgF2 Al2S3 K3N

15 Provide the chemical formulas for the following ionic compounds:
Tuesday, November 29th OBJECTIVE I will identify ionic compounds and name and write formulas for binary ionic compounds. WARM UP Provide the chemical formulas for the following ionic compounds: Barium chloride Magnesium oxide

16 Let’s make this more complicated!
When the metal in an ionic compound always forms an ion with the same charge, you don’t need to indicate the charge when you are naming the compound. HOWEVER, some atoms have the ability to form more than one type of ion which can make things confusing. I can’t refer to a compound of copper and oxygen as “copper oxide” because you wouldn’t know if I meant CuO or Cu2O

17

18 Questions for model 3 What is the most obvious difference between the names in model 3 and the names in model 2? Using model three, and keeping in mind that the charges of the compound MUST sum to zero, use the chemical formulas to: identify the charge on the copper cation in copper (I) oxide Identify the charge on the copper cation in copper (II) oxide Identify the charge on the iron cation in iron (II) chloride Identify the charge on the iron cation in iron (III) chloride

19 Identify the charge on the copper cation in copper (I) oxide
Using model three, and keeping in mind that the charges of the compound MUST sum to zero, use the chemical formulas to: Identify the charge on the copper cation in copper (I) oxide Identify the charge on the copper cation in copper (II) oxide Identify the charge on the iron cation in iron (II) chloride Identify the charge on the iron cation in iron (III) chloride

20 So what do the roman numerals mean?
Discuss with your partner what the roman numerals mean, use an example (other than the ones we just went over) to support your claim

Monday, December 4 OBJECTIVE I will name and identify covalent/molecular compounds WARM UP Consider this compound: Fe(HCO3)2 What type of compound is it? How can you tell? What is the correct name for the compound?

66

67 Model one – molecular compounds

71 Consider the compound NO
Check in - Consider the compound NO Which element, nitrogen or oxygen, would require a prefix in the name? Explain why

72 Be ready to share out your rules
Collaborate with your group members to write a list of rules for recognizing and naming binary molecular compounds from their chemical formula. Be ready to share out your rules

73 rules Binary molecular compounds can be regonized because they contain only two elements that are both non-metals In front of the name of the first element, write the prefix that corresponds with the subscript for that element. EXCEPT we never use mono on the first element In front of the name of the second element, write the prefix that corresponds with the subscript for that element and then the element name. Remove the ending from the second element and replace it with the suffix –ide Sometimes we drop the vowel of the prefix so the vowels do not double up.

74 Check in For each of the following compounds, indicate whether or not your naming rules apply: FeI3 ICl5 HBrO4
