Explanation:
As with all atoms known, electrons moves in discrete energy levels round a well defined orbit.
Protons are restricted to the nucleus of an atom. They occupy this small and massive position along with the neutrons.
Metals, have a large dense cloud of electrons.
- Every atom is made up of three fundamental particles.
- Protons, neutrons and electrons are these particles.
- Protons are positively charged and they occupy the tiny nucleus. Neutrons are found in the nucleus with them. They do not carry any charge.
- It is correct to infer their position as being fixed.
- Electrons occupies the bulk of the volume of the atom.
- They orbit round the tiny nucleus.
Therefore, it is safe to conclude that in metal conductors, electrons move but protons do not just like in every other atom.
