topic(s): orbital diagram

questions [8 points; 2 points / question]

1. what is the difference between an electron configuration (of an atom) versus orbital diagram (of an atom) ?

2. what is Hund's rule and the Pauli Exclusion principle ? what does the direction of an arrow in an orbital diagram represent ? how are they used to show an atom's orbital diagram ?

3. sketch the orbital diagram for __.

a. carbon

b. sulfur

4. based on your answers to the preceding questions and viewing the animation (requires either cdf player or mathematica installed on your computer, which should be installed on the computers in the classroom), describe how to draw any atom's orbital diagram ? for simplicity, assume that you already know the atom's electron configuration and you only have to show the electrons "outside" of the "brackets" in the electron configuration.
