This worksheet is the BEST!!! It shows students a few different things: 1: Electrons always fill the inner-most shell first, then work their way out. 2: 2, 8, 8 electron shell pattern 3: Basic structure of the PTofE 4: Patterns of valence electrons in the PTofE Don't lecture students on all of these facts; first have them complete this worksheet, then hold a group discussion on the patterns they found. The worksheet takes approximately 1 class period to complete. Discussion can occur same

Here is a pdf version of how I visually explain the ionic charge of an atom. I prefer to work our way through this as notes instead of instructing them via PPT. I then move on to ionic bonds where I show that the extra electrons come from other atoms, such as hydrogen.
