What number of valence electrons generally indicates a full outer energy level?

Simple machines make work easier. Most simple machines reduce the amount of effort force needed to move an object. In this wheel and axle system, the wheel and axle is used to pull a bucket up. A person turns the handle (P), using effort force.
