Three parts of an atom: electrons, protons, neutrons.
Conductors: metals, copper, mercury, iron, gold, aluminum, steel, chains, nails, spoons or forks, pennies (copper), steel scissors, lid of a mason jar, keys, a nickel etc.
This is because the rubbing creates a negative charge that is carried by electrons. When you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.
Ex of experiencing static electricity: when you get shocked on a trampoline due to the nylon material. When bouncing on a trampoline the bouncer can build up static. This is usually when the atmospheric conditions are very dry. Bouncing in these conditions can cause a build up of electrical charge.
