2.4 Water

• The water molecule has no overall charge, so it is neutral.
• As hydrogen and oxygen are both non metals, they are linked by a covalent bond. (Bond type)
• The bonds WITHIN water molecules are covalent bonds, the bonds BETWEEN water molecules are hydrogen bonds.
• STRONGEST BOND

  • Covalent
  • Ionic
  • Hydrogen

  WEAKEST BOND
• Electrons spend more time closer to oxygen because it is delta negative.
• The water molecule can be described as polar. (Arctic)
• Properties of water:

  • It is cohesive (sticks together) because it is polar. This is useful in plants when water moves up the xylem in a chain.
  • Has a high specific heat capacity because of its hydrogen bonds.
