So how about short "artsy" post to stimulate the mind? Maybe a Haiku and a cool slide show? What do you think?
Well, if I could actually hear your responses, I would hope that the answer would be, "Yes! Go for it!" So without further ado:
Here is a Haiku about why and how atoms form covalent bonds by sharing electrons:
Because the electron configurations of noble gasses (8 valence electrons and completely full outer shells) are the most stable of all configurations, when forming compounds, atoms strive to gain an octet. Thus, they will share the number of electrons needed for all atoms to have eight electrons in their highest energy level shells.
The image to the left shows how two Group 17 (7A) elements (two atoms with 7 valence electrons) can combine to create one single bond and a diatomic molecule.

Now, here is a short Animoto (an juiced up slide show) about five or six of the simplest molecular geometries and some household items that resemble these shapes. Enjoy!!
