Atom structure

All matter is made up of atoms. An atom Is made up 3 types of sub-atomic particles:

  • Neutron

  • Proton

  • Electrons

Atoms have no overall charge, but each particle in the atom has a specific charge. These charges are:

  • Protons - Positive (+) charge

  • Neutrons - Neutral (0) charge

  • Electrons - Negative (-) charge 

The protons and neutrons are present in the centre of the atom, called the nucleus and the electrons orbit the nucleus of the atom, on shells or energy levels
