Ionic, Covalent, and Metallic Bonding Day 8 – Metallic Bonding, Properties of Substances reading, and graphic organizer

Warm up FIND: Warm Up Page on your table GLUE: In Warm Up into Warm Up Section and answer questions TIME: 4 minutes WHEN DONE: Reread answers to the Metallic Bonding Video Water very polar Methanal somewhat polar one oxygen and one carbon Hexane non polar No hydrogen bonding in hexane so it is not bonding to other oxygen so it evaportaes easily

Agenda Review venn diagram Review Metallic bonding Properties of substances reading Demonstration: Properties Graphic Organizer

Learning Targets 3- I can describe how ionic, covalent and metallic bonds are formed between atoms 4- I can explain how interactions at the level of atoms, ions and molecules result in different properties in ionic, covalent and metallic substances

Review Venn Diagram Find: Your venn diagram in blue bin Time: 1 MINUTE WHEN DONE: Be ready to add more information

Venn Diagram of Ionic and Covalent Bonding Formed by ions Metal and a non-metal Electrons are transferred Attraction is between the cation and anion Non-metal and a non-metal Electrons are shared Attraction is between the shared electrons and the nuclei Both use valence electrons to bond Forces of attraction are between atoms Elements now have 8 valence electrons More stable

Metallic Bonding review How are ions in an ionic crystal different from ions in a metallic crystal? What happens to valence electrons in a metal? What are the free valence electrons called? What holds atoms together in a metallic crystal? Why do metals bend, but not break, when a force is applied to them? https://www.youtube.com/watch?v=Bjf9gMDP47s The ions in an ionic crystal are positive and negative, the ions in a metallic crystal are all positive. The valence electrons are given up by the metal atoms, and free to move in the spaces between atoms Sea of electrons The attraction between the positive metal ions and the negative “sea of electrons” Because the sea of electrons still attracts the positive metal ions, even if they shift or move. Shape can change, but attraction is still there.

Learning Target Check In TURN: To the Learning Target for this Unit PICK: Two colors of highlighter First color Highlight: Supporting Targets 3.1, 3.2 and 3.3 Write: Page # Column for “Covalent Tutorial” Second Color Highlight: Supporting Targets 4.1, 4.2 and 4.3 Write in: Page # Column for “Metallic Bonding”

Reading: "Properties of Ionic, Covalent and Metallic Substances” Take out: Properties of substances reading Show me: homework Highlight main idea in each paragraph I will: Stamp it for full credit TIME: 90 seconds When done: Grab a green card from blue bin

Reading: "Properties of Ionic, Covalent and Metallic Substances” reRead and Annotate: Properties of substances Focus annotation on: What surprises you? What does the author assumer I know? Sentence starters for margin notes: “This is important because. . .” “This is connected to. . .” “I am confused about. . .” TIME: 14 Minutes When done: tape/glue reading into notebook, along with work that has been passed back (lab and ionic and Covalent bonding assignments) Minimum ONE NOTE PER PARAGRAPH!
