Unformatted text preview: Octet Rule representative elements want to have (share) 8 electrons to achieve the noble gas stability Except H only wants 2 electrons (duet rule ) Rules for Drawing Lewis Structures o 1. Must include all valence electrons Sum all of the valence electrons and show all valence electrons in Lewis structures o Anion add 1 electron for each negative charge o Cation subtract 1 electron for each positive charge o 2. Atoms that are bonded share one or more pairs of electrons o 3. Electrons are arranged so all atoms have a filled valence shell (octet rule & duet rule )...
