Electron Sharing
-chemical bond formed when 2 atoms share electrons
F. + .F
F:F
How many bonds
-single bond
F:F
-double bond
O::O
-triple bond
:N:::N:
Each bond involves 2 electrons
Properties of Molecular Compounds
-lower boiling point than ionic bonds
-poor conductors of electricity
Sharing of Electrons
- polar: Some atoms pull more on the electrons than others
H : Br from

- nonpolar: Equal pull between atoms

Attractions between molecules
difference in the attractions between molecules lead to different properties
in polar and non olar compounds
polar - dissolves in water
nonpolar - do not dissolve well in water (i.e. oil)
