Ionic, Covalent, and Metallic Bonding Day 9 – Check for understanding

Warm Up DRAW: Lewis Dot structure for Sulfur Dibromide (SBr2) REMEMBER: FIND The TOTAL number of valence electrons and electron pairs CREATE bonds using electron pairs EACH ATOM in the molecule should have 8 valence electrons Use X’S AND LINES to represent shared valence electrons Use dots to represent unshared valence electrons TIME: 8 MINUTES WHEN DONE: Turn in your homework (Graphic Organizer for Properties)

Agenda Review Graphic Organizer Pop Quiz: Six Questions Progress Reports

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
