1. Metallic Bonding, Lewis Structures, Mixed Ionic and Covalent Bond Practice

2. Evaluation/ Assessment
Objective
Today I will be able to:
Explain the movement of electrons in metallic bonds
Draw Lewis Structures to represent the valance electrons in an atom
Correctly name and write formulas for ionic and covalent compounds
Evaluation/ Assessment
Informal assessment – Listening to group interactions as they complete the ionic and covalent Lewis structure practice and the naming compounds practice.
Formal Assessment – Analyzing student responses to the lab questions and the naming ionic and covalent compounds practice.
Common Core Connection
Build Strong Content Knowledge
Reason abstractly and quantitatively
Look for and express regularity in repeated reasoning

8. Metallic Bonding Notes

9. Metallic Bonds
Loosely bound valance electrons which are called mobile electrons because they are free to move around
delocalized
Allow the transition metals and rare earth metals to have multiple charges

10. Electron Movement in Metallic Bonds

11. Properties of Metallic Bonds
Solids at room temperature (except Mercury)
Ductile
Malleable
Good conductors

12. Drawing Lewis Structures

13. Lewis Structures
Visual representation of the number of valance electrons in an atom

14. How to draw Lewis structures
Write the symbol of the element
Pretend there are 4 sides
Use dots to represent the valance electrons around the symbol
Place one dot on each side of the element before you form pairs
Exception: If there are only 2 valance electrons, they both go on the same side
