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

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 nonmetal • Both use valence electrons to • Electrons bond are shared • Forces of attraction are between atoms • Attraction is between • Elements now the shared have 8 valence electrons and the • More stable nuclei

METALLIC BONDING REVIEW 1. How are ions in an ionic crystal different from ions in a metallic crystal? 2. What happens to valence electrons in a metal? 3. What are the free valence electrons called? 4. What holds atoms together in a metallic crystal? 5. Why do metals bend, but not break, when a force is applied to them?
