Ch. 11 - Chemical Bonds

I. Why Atoms Combine(p.298-302)

Chemical Formula

Chemical Bond

Stability

a chemical formula

1 oxygen atom

2 hydrogen atoms

A. Chemical Formula
  • Shows:

1) elements in the compound

2) ratio of their atoms

H2O

b chemical bond
B. Chemical Bond
  • Strong attractive force between atoms or ions in a molecule or compound.
  • Formed by:
    • transferring e- (losing or gaining)
    • sharing e-
c stability

Ne

C. Stability
  • Octet Rule
    • most atoms form bonds in order to have 8 valence e-
    • full outer energy level
    • like the Noble Gases!
  • Stability is the driving force behind bond formation!
