Title: CHEMICAL BONDING


1
CHEMICAL BONDING
  • The most important property of an is how it
    combines

2
Outcomes/Objectives Things you will be able to do
  • Define chemical bond and relate to valence
    electrons
  • Predict an elements chemical properties using the
    number of valence electrons.
  • Draw Bohr models and electron dot diagrams for
    elements.
  • List three types of bonding
  • Describe how an Ionic Bond forms and the force
    that keeps them together.
  • Define Ion
  • QUIZ
  • Describe how a covalent bond forms.
  • Define Molecule
  • Recognize and describe polyatomic ions.
  • Test Preparation
  • Study Daily, Complete All Assignments ,Stay 10th
    , Stay on Task (Focus),
    PLEASE ask for HELP when LOST

3
Chemical Bond
  • Attractive force that holds or
    together
  • Atoms of different Elements can combine with each
    other in many different ways
  • Example

4
ELECTRONS AND BONDING
  • e- are arranged into
  • Energy Levels can hold more e- as you move
    farther away from the nucleus via (2level2)
  • For bonding reasons in general atoms will form
    compounds if the bonding results in both Atoms
  • The of valence e- determines an elements

5
  • Electron Dot Diagrams of Elements only show the
    symbol surrounded by dots that represent the of
    valence electrons. Create e- dot diagrams for
    elements 3 to 10.
  • Make Bohr Models of Elements 3 Through 10

6
CHEMICAL BONDING AND STABILITY
  • Atoms want to have stable electron
    configurations. And in order to be stable they
    need in their outer energy level. This can
    be achieved by bonding with other atoms.
  • transfer of electrons from atom to atom
  • sharing of electrons
  • the attraction between a metal cation and
    the shared electrons that surround it

7
Ionic Bonds Transfer of e-
  • Atoms can
    in their outer level (shell)
  • Form between
  • Stay together because of an
    between oppositely charged

8
IONS
  • METALS
  • tend to
  • form
  • than the atoms that make them up
    b/c the nucleus
  • NONMETALS
  • tend to
  • form
  • than the atoms that make them up b/c
    the nucleus

9
COVALENT BONDING
  • Sharing
  • Form between.
  • Form
  • Can be
  • More

10
COVALENTLY BONDED IONS
  • _________________
  • a group of covalently bonded atoms that has an
    electric charge due to
  • Example
  • Metallic Bonds
