Students completed the "Element Code" WS (38 pts), a "Periodic Table Relationships" WS (38 pts) and took the first polyatomic ion test (20 pts). All were completed in class except the "Periodic Table Relationships" WS.  We will have another "Polyatomic Ion" Test (20 pts) and a Chemical Bonding Test Voc. Test on tomorrow.  The Chemical Bonding Chapter Test (100 pts) will be on Thursday.

Students watched a podcast on "How to write Covalent Formulas" and How to Name Covalent Compounds.  Afterwards, students completed two worksheets.  "Writing Covalent Formulas" (50 pts) was completed for homework while "Naming Covalent Compounds" (50 pts) was completed in class.  Students were also made aware of the Polyatomic ion Test set for Tuesday, Wednesday and Thursday.  They were also advised of the coming Chemical Bonding Voc. Test on Wednesday and Chapter Test on Thursday.

2-1

We took notes on "what polyatomic ions are", "how polyatomic ions are used", and copied the list of 16 polyatomic ions that we were to have memorized.  Then, we saw a podcast on naming Ionic Compounds with Polyatomic Ions.  For classwork/homework, we completed a worksheet on "Naming Ionic Compounds Containing Polyatomic Ions". (50 pts)

2-2

After observing a podcast from PapaPodcast on "Writing Formulas with Polyatomic Ions" we worked 5 sample problems.  Then, we completed the worksheet on "Writing Ionic Formulas with Polyatomic Ions". (50 pts)

2-3

After taking notes from the Chemical Bonding PPT, we learned the prefixes for naming Covalent compounds and how Covalent compounds are different from Ionic Compounds.  Then, we concluded the period with homework on "Naming Covalent Compounds" WS (50 pts)

 

Class began with students completing a worksheet called, "Naming Ionic Compounds" (50 pts). Students learned how to write ionic formulas with polyvalent ions (transition elements) and then take the formulas with transition elements and write the formulas.  They had two worksheets for classwork/homework; "Writing Ionic Formulas with Polyvalent Atoms" (50 pts) and "Naming Chemical Formulas with Polyvalent Ions" (50 pts)

Students were able to complete the notes on Oxidation numbers for elements on the Periodic Table.  They learned to determine oxidation numbers for the transition elements and how to write chemical formulas for ionic compounds using the Periodic Table.  They also viewed a Youtube presentation on how to correctly write Ionic Formulas.  Homework consisted of completing a "Bonding & Chemical Formulas" WS (100 pt)

26 - Students took notes from the PowerPoint as we discussed the concepts of Ionic Bond characteristics, subscripts and how to name ionic compounds.

27 - Students took information on what a chemical formula is, what it includes and how to determine oxidation numbers in an ionic formula.

Students took notes from the PowerPoint on Chemical Bonding.  We learned what forms chemical bonds, why they form and how to determine the difference in ions and atoms.  Finally, we learned the difference in ions and atoms of the same elements.

Students began the PPT and notes on Chemical Bonding.  We reviewed Atomic Structure and why atoms gain or lose electrons.  Also, emphasizing Group names and characteristics.

Students began reading the "Chemical Bonding" chapter and answered the Review Questions during class.  The Review Questions were worth 60 pts (Silver).  They were to be completed by the end of the period.

All 10th graders took the ACT Aspire Test on the Chromebooks during class.  There was no homework for the weekend.
