True. The protons and neutrons together are dense and comprise most of the mass of the atom. The electrons "circle" around in a "cloud" so there is empty space in between the electrons.
True, most of an atom's volume is the space in which electrons move.
true
False. Mechanical waves require a medium, such as air or water, to travel through. They cannot propagate through empty space because they rely on the vibration of particles in the medium to transfer energy.
False. Most of the volume occupied by a piece of copper is taken up by the electrons moving around the copper nuclei. The size of the atomic nuclei is very small compared to the overall size of the atom.
false
Technically false; it's full of virtual particles, photons, gravitons (if they exist), and possibly other gauge particles. However, if this is a homework question and you're not in university physics, the answer your teacher is probably looking for is "true."
