Used for _________________________.

Full set of valence electrons is _____________

- Octet rule ( we will discuss this in a future chapter)

Lewis Structures and electron dot diagrams

• Show valence electrons around the element’s _________________

• Can put at most _____ electrons next to each other

• To draw – place 1 electron at a time around the symbol in 4 locations (top, side, bottom, and other side) before doubling up until all valence e- are used.
