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.
The Elements
Students began work on the "Elements" Sec. Rev. WS (90 pts) and completed in for homework. They were made aware of the Elements Voc. Test on Tuesday and Ch. Test on Wednesday.
Chemical Bonding
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.
The Elements
2-1
We continued taking and comparing notes from the students outlines with the teachers notes from the PowerPoint on "the Elements". We covered the Elements in groups 3A -6A in terms of uses and main group characteristics.
2-2
After reviewing the key concepts of Groups 3A-6A, we continued the comparison in Groups 7A, 8A and began key Transition Elements.
2-3
Continuing to review the Main Group elements key characteristics and uses of major elements, we finished the Transition element keys and elements. Magnetism and metallurgy were discussed using key elements in the Transition Elements.
Chemical Bonding
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)
Elements
We continued the PowerPoint presentation covering groups 3A - 5A, their characteristics and their uses. Emphasis was placed on uses and locations of the elements in compounds.
Polyvalent Formulas and Naming
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)
S-Block Elements and Uses
Students turned in the notes on Sec. 1 & 2 from the homework. We compared notes from the students to the notes from the PPT on Elements and the chapter.
Oxidation Numbers; Writing Ionic Formulas
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)
Chemical Bonding
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.
