Lewis Dot Structures

In today's lecture we learned about Lewis Dot Concept that help to show the chemical bonding occurring within a molecule. In order to make a Lewis Dot Concept, a dot must be placed around the element to represent each electron in its valence shell. The dots must be placed going clockwise and only pairing up once four electrons has been exceeded.






One of the rules we learned regarding electrons in the valence shell was the octet rule. The octet rule states that, with a few exceptions, an atom can not have more than eight electrons in it's outer shell. An example of an exception is beryllium. Beryllium, despite the predicted four valence electron, requires six valence electrons in order to be stable.
