Students continued the PowerPoint on the Elements of Groups 6A & 7A, the characteristics of the groups and their element's uses. The Vocabulary Test on this chapter is planned for Monday. All 10th graders will be taking the ACT Aspire Test on Friday.
Chemical Bonding
Students learned how to write chemical formulas for transition metals using Roman numerals. We also went in reverse and learned how to take chemical formulas for transition elements and name chemical formulas w/transition elements. They had two worksheets to complete, Naming Ionic Compounds with Polyvalent Ions (50 pts) and Writing Chemical Formulas w/Polyvalent Ions (50 pts). One worksheet is due during GPS and the other tomorrow. Tenth grade students will be taking the ACT Aspire Science Test via laptop in class on Friday.
The Elements
We continued the PowerPoint "The Elements" as we covered the general characteristics of the Groups 4A-6A and the elements in them and their uses.
Chemical Bonding
Students reviewed the terms oxidation number and then watched a podcast by PoppaPodcast on "Writing Chemical Formulas for Binary Ionic Compounds". Then, we worked a few practice problems for writing binary ionic formulas. We concluded class by completing the "Writing Ionic Formulas" (50 pts) worksheet. Those that did not finish were allowed to complete the worksheet at home.
The Elements
We continued the PowerPoint "The Elements" as we covered the general characteristics of the Group 2A & 3A elements and properties of Groups 2A and 3A.
Chemical Bonding
Students continued taking notes on "Chemical Bonds" and learned the new term oxidation number, how to determine oxidation number using the Periodic Table and began the steps for learning how to write chemical formulas for ionic compounds using oxidation numbers.
The Elements
We continued the PowerPoint "The Elements" as we covered the general characteristics of the Group 1 & 2 elements and properties of Groups 1 & 2.
Chemical Bonding
Students continued the notes from the PowerPoint on the characteristics of ionic compounds, how to determine the charge on ions of metals/nonmetals and the rules for naming Ionic Compounds. Then, the students completed the "Valence Clues" WS (40 pts) and the "Naming Ionic Compounds" WS (50 pts).
Elements
Students began taking notes on the general characteristics of the groups of the Periodic Table and uses for the elements within the groups from the PowerPoint on The "Elements"
Chemical Bonding
Students completed the "Compounds" Review Questions (60 pts) in class. We then began the PowerPoint and notes on Chemical Bonding to explain what chemical bonding is and how it is needed for atoms on the Periodic Table.
