Students took notes on oxyanions and polyatomic ions. We then viewed a podcast on how to name compounds containing polyatomic ions and how to write ionic formulas with polyatomic ions. They were given worksheets on "Naming Ionic Compounds with Polyatomic Ions" (50 pts) and "Writing Ionic Formulas with Polyatomic Ions" (50 pts) for homework. They will have a polyatomic ion test on Friday.
Ionic Compounds
We continued and reviewed the 3 different types of Ionic Compounds Formulas and how to write them. We then began comparing/contrasting ionic & Covalent formulas.
Students learned the difference in main group ionic formulas and chemical formulas w/polyvalent ions. We then learned how to write formulas with transition elements and take formulas w/transition elements and name them. They were given 2 WS's for homework on "naming Ionic Formulas w/Polyvalent Ions" (50 pts) and writing "Polyvalent Formulas" (50 pts).
Polyatomic Ion Formulas
We quickly had a poptest on naming the symbols, and charges for polyatomic ions. Then, students watched a "Naming Ionic Compounds w/Polyatomic Ions" podcast. Then, after working seven practice problems, they were given the "Naming Polyatomic Ions Formulas" WS (50 pts). They were advised to study for the Polyatomic Ion Test on Thursday.
Ionic Formulas
14th - Valentines Day
Students learned how to write chemical formulas for ionic compounds. After watching a short podcast on writing Binary Ionic Formulas, they completed the Bonding and Chemical Formulas WS (100 pts)for homework.
15th -
Students completed the "Naming Ionic Compounds" WS (50 pts) in class. We began to learn what polyvalent ions are and how to name chemical formulas with them.
Polyvalent Formulas & Polyatomic Ions
14th - Valentines Day
Students learned what a polyvalent (transition) element is. We also learned how to write ionic compounds with polyvalent elements and how to name compounds with polyvalent elements. They had two worksheets for homework; Naming Ionic Compounds with Polyvalent Ions (50 pts) and Writing Ionic Formulas with Polyvalent Ions (50 pts).
15th -
Students learned what a polyatomic ion is, how to identify them, their formulas and charges. They were given a list of polyatomic ions to learn. Then, we learned how to name ionic compounds with polyatomic ions. They were to complete the worksheet, "Naming Compounds Containing Polyatomic Ions" for classwork (50 pts).
Ionic Compound Characteristics
Students continued reviewing the notes from the PPT on Ionic Compounds, their characteristics and Group Oxidation numbers.
Writing Ionic Chemical Formulas
Students went over the portion of Chemical Bonds notes on Writing Ionic Chemical Formulas and Oxidation numbers. Then we watched a podcast on Writing Binary Formulas on Ionic Compounds. Students then completed the "Bonding & Chemical Formulas" WS (100 pts). They were assigned a "Writing Ionic Formulas" WS (50 pts) for homework.
Ionic Compounds
We went over the PPT notes on how Ionic Compounds are formed, ionic charges and how to use the Periodic Table to determine bond type.
Chemical Bonds
We went over the notes on Chemical Bonds PPT and began to learn how to name ionic compounds, their characteristics, and how to determine ionic charge. They were given the "Valence Clues" WS (40 pts) and "Naming Ionic Compounds" WS (50 pts). We will continue studying Ionic Compounds this week.
