Proton- a particle carrying a positive charge
Electron- a particle carrying a negative charge
Neutron- a particle that carries no charge
Nucleus- this is the center of the atom, which holds the protons and neutrons
Electrical Current- this is the amount of pressure created from electrons being
attracted to protons
6. Quarks- the particles that are inside the neutron and proton; always 3 of them in a
neutron and proton
7. Gluons- these are the particles that hold together the quarks inside the neutrons
and protons
8. Insulator- a material that resists the flow of an electric current
9. Conductor- a material that allows the flow of an electric current
10. Isotope- when an atom has more neutrons than protons
11. Conventional Theory- states the opposite, that energy flows from positive areas to
negative areas because of the energy that is being released
12. Electron Theory- states that since electrons are negatively charged, a current
flows from the most negative point to the most positive point in a circuit
13. Hole-Flow Theory- a third theory that explains current flow, which is based on
both the conventional and electron theories
14. Ion- an atom that has a positive charge, that is, having one more proton than
electron
