    Work in groups on these problems. You should try to answer the questions without referring to your textbook. If you get stuck, try asking another group for help.

    This tutorial is designed to demonstrate the step-by-step process of drawing electron dot formulas. In the typical lecture, you end up with the final formula but you may not remember all of the individual steps that were done in drawing the formula. These tutorials allow you to repeat any step of the process until you understand each step. You can return to any of the previous pages by using the "back" button on your browser.
