Answer:
The protons and the neutrons are found in the nucleus of an atom.
Explanation:
Atoms are best described as the smallest unit of any matter.
Protons can be described as part of an atom which carries a positive charge. The protons are enclosed in the nucleus of the atom.
The neutron is the part of the atom that carries zero charge. The neutron is also enclosed in the nucleus of the atom.
The electrons can be described as the part of an atom that carries a negative charge. The electrons move around the nucleus in orbits.
