List the steps for making a Lewis Structure.

  1. Add valence electrons

  2. Single atom is central atom

  3. Make single bonds from central atom to other atoms

  4. Each bond equals 2 electrons and subtract 2 from total valence electrons

  5. Add lone pairs of electrons (dots) on other elements to complete octet rule

  6. Change single bonds into double bonds if there aren't enough electrons

500

What is the shape of BF3.

trigonal planar

Give an example of a hydrogen bond.

H2O
