Page 1: Wonderful World of Water. H2OH2O Oxygen is more electronegative then hydrogen. Electrons move towards the oxygen giving it a slight (-) charge and leaving.

Wonderful World of Water

Page 2: Wonderful World of Water. H2OH2O Oxygen is more electronegative then hydrogen. Electrons move towards the oxygen giving it a slight (-) charge and leaving.

H2O

• Oxygen is more electronegative then hydrogen.

• Electrons move towards the oxygen giving it a slight (-) charge and leaving the hydrogens with a slight (+) charge.

Hydrogen Bonding

• The slight charges makes water polar.• The polarity causes hydrogen bonding
