Title: Metallic Bonding, Lewis Structures, Mixed Ionic and Covalent Bond Practice


1
Metallic Bonding, Lewis Structures, Mixed Ionic
and Covalent Bond Practice
2
  • 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

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

Illustrate Ionic and Covalent Bonds with Lewis
Structures
  • Complete the worksheet using the examples. Ask
    Ms. Ose if you need help with questions.

20
Ionic and Covalent Compounds Practice
  • Complete the practice with the people around you.
    Whatever you do not finish in class will become
    homework. We will review next class.
