MO THEORY I. Shapes and Signs on Atomic Orbitals: Atomic orbitals are visual pictures of mathematical formulas, which, (when squared = 2), tell us the probability of finding an electron at each possible position in space. These functions, like any ma
LEWIS DOT DIAGRAMS AND ASSIGNING FORMAL CHARGES Bonds and Lone Pairs:
Each covalent bond between atoms usually contains 2 electrons. Between 2 atoms we can have any of the following: a single bond (2 electrons) a double bond (4 electrons i.e., 2 2-e
