Water molecule structure

• what sort of structure do water molecules have?

  a simple structure
• what is a molecule of water?

  one atom of oxygen joined to two atoms of hydrogen by SHARED ELECTRONS
• Why is water a polar molecule?

  • Because the shared negative H2 electrons are pulled towards the oxygen atom, the other side of each H2 atom is left with a SLIGHT POSITIVE CHARGE
  • The UNSHARED negative electrons on the oxygen atom give it a SLIGHT NEGATIVE CHARGE
  • This makes water a POLAR MOLECULE
• Explain water being a polar molecule?

  it has a partial negative charge on one side and a partial positive charge on the other
• greek letter 'delta'

  Delta positive :

  
• greek letter 'delta'

  delta negative:

  
• what do the slighlty negatively-charged oxygen atoms do?

  attract the slightly positively-charged hydrogen atoms of the other water molecules

  • this attraction is called hydrogen bonding and gives water some of its useful properties
• what does hydrogen bonding give water?

  some of its useful properties
