7. Have an understanding of the three subatomic particles of the atom; their charge; and location:
1) Protons (positive charge – located within the nucleus)
2) Electrons (negative charge – located outside the nucleus in specific energy levels)
3) Neutrons (neutral charge – located within the nucleus)
