Naming Unit
November 11-20 (2015)
Day 1: Naming Binary Ionic Compounds
Objectives (SWBAT):
Physical Science 5- Name ionic compounds, including those with transition metals
-write formulas for ionic compounds from their names
Evaluated by:
Binary Ionic Compounds Worksheet
Class structure:
Do Now: What is the difference between S-2, SO4-2, and SO3-2? Name the polyatomic ions.
1. Engage- The teacher will review writing ionic formulas from their charges (crisscross) and students will
practice this skill on part A of the worksheet.
2. Explore- The teacher will refer back to the Do Now to explain how to name nonmetal anions then
explain how to name any elemental ions and demonstrate this with problems 9-15. Students will
practice this skill with problems 16-22.
3. Explain- The teacher will connect these two sections and show students how to convert a binary ionic
compound’s name to a formula with problems 23-29. Students will practice this skill and show all work
for problems 30-36.
4. Elaborate- Students will solve 20 mixed problems for homework on the back of the worksheet and will
show all work for name to formula conversions.
Summary: Ionic compounds are named with the name of the cation, then the name of the anion. When writing ionic
formulas from their names, the crisscross method is vital to write the correct formula.
Day 2: Naming Ternary Ionic Compounds
Objectives (SWBAT):
Physical Science 5- Name ionic compounds, including those with polyatomic ions
-write formulas for ionic compounds from their names
Evaluated by:
Ternary Ionic Compounds Worksheet
Class structure:
Do Now: Name the following compounds- CaS and CuS.
1. Engage- The class will review naming various types of ions (representative metals, transition metals, and
nonmetals).
2. Explore- Students will correct any problems from day 1’s homework based on the review during the
engage (10 minutes).
3. Explain- The teacher will explain the term ternary, how to recognize these compounds, and review the
procedure for writing their formulas (crisscross with parentheses).
4. Elaborate- Students will complete the ternary ionic worksheet showing work for all name to formula
conversions.
Summary: Naming ionic compounds that contain a polyatomic ion is the same as naming binary ionic compounds- cation
name then anion name. The trick is recognizing that the compound contains a polyatomic ion. As a helpful hint,
remember that a compound can only ever have two names. If you have more than two elements (two names), a
polyatomic ion must be present.
Day 3: Mixed Ionic Naming
Objectives (SWBAT):
Physical Science 5- Identify (name) ionic compounds and distinguish between binary and ternary bonds
-write formulas for ionic compounds from their names
Evaluated by:
All Ionic Compounds Worksheet
Class structure:
Do Now: What is the name for Na3PO4 and how did you recognize this?
1. Engage- The teacher will review how to recognize binary and ternary compounds then go over the
answers to day 2’s worksheet.
2. Explore- Students will complete the mixed ionic practice worksheet for the day.
3. Explain- Students will show work when writing formulas from names.
4. Elaborate- Students will add the naming rules to their labeled periodic table.
Summary: In naming ionic compounds, check to see if the first element is a transition metal. If not, write the name as it
appears on the periodic table. If not, write the name and put the charge of the metal in roman numerals following the
name. Then move to the anion. If it is a nonmetal on the periodic table, name the element but change the ending to –
ide. If it is more than one element, the anion is a polyatomic ion. Look up the formula on your chart and copy the name
exactly as it appears.
Day 4: Naming Acids
Objectives (SWBAT):
Physical Science 5 (and 7) – Name acids using formulas and write formulas for acids from their names
Evaluated by:
Naming Acids Worksheet
Class structure:
Do Now: What is the formula for Cu3(PO4)2? (Hardest type of ionic compound to name)
1. Engage- Review the difference between binary and ternary ionic compounds.
2. Explore- Students will highlight all the formulas on the back of the page in yellow if binary and in blue if
ternary.
3. Explain- The teacher will explain the difference in naming these two types of acids
a. Binary: first word has a prefix of hydro, then the name of the anion, then a suffix of ic and the
second word is acid
i. Example of HCl would be named hydrochloric acid
b. Ternary: first word is the name of the polyatomic ion with a suffix of –ic replacing –ate or a suffix
of –ous replacing –ite and the second word is acid
i. Example of HClO2 would be named clorous acid because the polyatomic ion is chlorite
ii. Example of HClO3 would be named cloric acid because the polyatomic ion is chlorate
c. Then, the students will highlight all the names on the back of the page yellow if binary and blue
if ternary.
4. Elaborate- Students will use their notes to complete the names and formulas on the worksheet.
Remember to show work when converting names to formulas.
Summary: Binary acids are named with the prefix hydro, the suffix –ic and the root of the anion element followed by the
word acid. Ternary acids are named with the root polyatomic ion and the suffix –ic for –ate ions and –ous for –ite ions.
There is no hydro- prefix for ternary acids.
Day 5: Naming Covalent Compounds
Objectives (SWBAT):
Physical Science 5 – Name molecular (covalent) compounds from formulas and write formulas for molecular compounds
from their names
Evaluated by:
Molecular Compounds Worksheet
Class structure:
Do Now: What is the formula for hydrosulfuric acid?
- The teacher will explain the dual nature of hydrogen- a nonmetal that appears on the left hand side of the
table. Hydrogen forms covalent compounds by sharing electrons but its formula is written in the same way as ionic
compounds (crisscross).
1. Engage- Students will use context clues to guess what a foreign word (Greek) is to introduce the idea
that Greek is needed to name covalent compounds.
2. Explore- Students will use the notes sheet to name covalent compounds and to write formulas from
names.
3. Explain- Students will make flashcards of the Greek prefixes with key words to aid in recall for each
prefix (example tri= tricycle= 3 wheels= 3 atoms)
4. Elaborate- Students will complete the 20 mixed problems on the back of the worksheet to begin
preparing for day 7’s test.
Summary: Covalent compounds are named with Greek prefixes that indicate the number of atoms of that element.
Mono is only used when one atom of oxygen is present.
Day 6: Review for Naming Quiz
Objectives (SWBAT):
Physical Science 5 and 7- identify, name, and write formulas for ionic compounds, acids, and covalent compounds
Evaluated by:
Naming Review
Class structure:
Do Now: Name the following compounds- NaBr, CH4, K3PO4, CuCl2, HF, and HNO3.
1. Engage- Students will be called to the front (names randomly generated) to give the answers and
explanations for the back side of day 5’s worksheet. The class will review how to distinguish among
compounds and then name them.
2. Explore- Students will write formulas and names for a list of thirty mixed compounds.
3. Explain- Students will peer check their answers as they progress through the worksheet and come to
agreements for answers by explaining naming rules.
4. Elaborate- Students will check their answers to the naming review online if there is not time to do this as
a class.
Summary: When naming a compound from a formula or writing a formula from a name, the first and most important
step is to identify whether the compound is ionic, covalent, or an acid.
Day 7: Test- Naming (Day 8: Retakes-until 84% proficient or greater)
Objectives (SWBAT):
Physical Science 5 and 7- demonstrate at least 84% proficiency over the material from this unit.
Evaluated by:
Test- Naming
Class structure:
Do Now: Take out something to write with, open your binder to the table of contents and place it on the back
bench, and move your bags to the A/C
TEST
Summary: There are two main types of chemical bonds that are fundamentally different. The different elements used result in
different electron activity which results in different molecular structures with different physical and chemical properties.
