" Week #1      o organic chemistry: the study of carbon based molecules and a few other        elements (primarily nitrogen, oxygen, and hydrogen)   Electron Configuration     o Electrons are held in orbitals.    o Electron configurations tell us where electrons are located.     o example #1:             2  2   2        Carbon: 6 electrons, 1s 2s 2p    o example #2:        Hydrogen: 1 electron, 1s1    o example #3:                              2  2   4        Oxygen: 8 electrons, 1s 2s 2p  Lewis Dot Structures      o Lewis dot structures help us determine how bonds form between atoms.    o These structures deal with valence electrons (the outermost electrons)        because these are the electrons involved in bonding.    o Atoms are most happy (stable) when they have 8 valence electrons.
