Structure of an ATOM

• Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
• The first shell consists of 2 electrons, the the rest of the shells element needs has a maximum capacity of 8 electrons.
