Answer:
The options are not shown, however the attached picture should show the parts of an atom and the relationships between the three basic parts of an atom being Protons, Neutrons and Electrons.
In the nucleus of an atom, there are both Neutrons and Protons whilst the rings of the atom will contain the electrons.
The protons carry a positive charge and the electrons a negative one.
When the protons and neutrons are added together, these will give the mass number of the atom so the mass number of this atom is 32.
For a neutral atom, the Protons and the Electrons should be equal. Notice how there are 16 protons (+) in the nucleus and 16 electrons (-) on the rings.
