Answer

Brief Explanations:

The part marked "A" is the electron - shell. Electrons are negatively charged and are located in these shells. The nucleus contains most of the mass. The nucleus is mostly empty space in a different context related to the sub - atomic particles within it. The nucleus is composed of protons and neutrons, not electrons.
