Slide 1 _____. _____. _____. Molecular Shapes Putting it all together _____. _____. _____. _____. Slide 2 _____. SeO2. One more example: _____. What's the Lewis Dot Structure for SeO2? 1st question: _____. What's the total # of valence electrons? _____. _____. _____. _____. Slide 3 _____. _____. _____. _____. _____. _____. _____. Slide 4 _____. Dot structure for SeO2. SeO2. _____. 18 total valence electrons. Next question: _____. What's the central atom? _____. _____. _____. _____. Slide 5 _____. Dot structure for SeO2. _____. O Se O. Now? Fill the octets _____. _____. _____. _____. _____. Slide 6 _____. Dot structure for SeO2.. _____. :O Se O: . Once we've filled the octets, what do we do? _____. Check the total # of valence electrons 20 total electrons too many! So, what do we do? Make a bond! _____. _____. _____. _____. Slide 7 _____. Dot structure for SeO2.. _____. :O = Se O: . Are we done? _____. Check the formal charges. FC(left O) = 6 2 4 = 0. FC(Se) = 6 3 2 = 1.
Slide 16 Dot structure for SO 2:O = S = O: ¨ ¨ ¨ S can have an expanded octet, we can make a bond out of 2 electrons from O without eliminating any S electrons?
