Structure and bonding

What is here?

The four models here are chosen because:

  • sodium chloride has a giant lattice structure with ionic bonding between oppositely charged ions
  • iodine exists as simple molecules with weak van der Waals’ forces between the molecules
  • graphite and diamond have a giant structure with covalent bonding.

Use your mouse (or finger on touch devices) to move or scale molecules. Double tap to stop and start each animation.
