Task 3 Atomic Structure
Proton small particle with a positive charge
found in the nucleus of the atom
Neutron a particle with no charge found in the
nucleus of the atom.
Electron very small negatively charged particle
found in the space surrounding the nucleus
We can find the atomic structure by using the
atomic number and mass number. These give us the
information needed to see how the atom is built
up.
Atomic Number the number of protons in the
nucleus of an atoms the number of electrons
Mass Number the number of protons the number
of neutrons
