Editor's Notes
*little blue arrows illustrate FORCE
Which elements would NOT hold their electrons tightly? (those with unpaired electrons or unfilled energy shells)
*NOT flow or constant movement of electrical energy GOOD CONDUCTORS = metals, water
Antistatic mats and wrist strap Electricity always "flows downhill" - it looks for a "ground" or neutral - The planet is a good conductor, and it's huge, so it makes a handy return path for electrons. "Ground" in the power-distribution grid is literally the ground that's all around you when you are walking outside. It is the dirt, rocks, groundwater and so on.
