Now, let’s practice making Lewis valence electron dot structures.

Directions:

1. Drag the symbol for the element to the box, then click the "Next" button.
2. Drag and drop the appropriate number of valence electrons based on the group number.
3. Remember, electrons are all negatively charged, and like charges repel each other. Electrons will fill orbitals one at a time until there is a lack of open space to minimize these repellent negative charges. Therefore, put only one electron on each of the four sides until they are all filled.
