- - - - water
    - - ionic bonds are formed from the transfer from electrons, so they create ions. covalent bonds create molecules since they share electrons. this means simple molecules are covalent.
    - - they have low melting points and high boiling points. for simple molecules, the intermolecular force doesn't need as much energy to overcome as a strong covalent bond does. the intramolecular force still stays intact since it requires much more energy to break. we use simple molecules like oxygen to breath or H2O to drink water
- - - - giant covalent structures, as the name suggests are covalent. they are all atoms joined together and share electrons.
    - - giant covalent structures have high boiling and melting points. this is due to the large amount of energy required to break the large
        covalent bonds. things with giant covalent bonds like diamonds have high melting points and dont break easily, this is why they are used as cutting tools since they also don't conduct elecricity.
    - - graphite
      - sand
      - diamonds
