Volume occupied by electrons Nucleus containing protons and neutrons- -10-4 Å- -1-5 Å– A Figure 2.10 The structure of the atom. A cloud of rapidly moving electrons occupies most of the volume of the atom. The nucleus occupies a tiny region at the center of the atom and is composed of the protons and neutrons. The nucleus contains virtually all the mass of the atom.
