Solution

Structure of an atom.

Position of the subatomic – particles.
Atom consist of three sub-atomic.
Particles: 1. Protons, 2. Electrons, 3. Neutrons

  1. The nucleus of the atom contains the protons (positively charged) and the neutrons (no change)
  2. The outermost regions of the atom are called electron shells and contain the electrons (negatively charged)
  3. The protons have a positive charge while neutrons have a neutral charge.
  4. Electrons circle around the nucleus of an atom, they are negatively charged.
