If the atom's outer boundary is established by the "mean radius of the outermost electron orbital" or something like that, the atom is waaaaaaaaaaay over 99% free space. The hydrogen atom has a diameter over 100,000 times the diameter of the proton in it's nucleus.

Thanks for the feedback!
They are mostly empty space apart from the protons and neutrons in the middle of the atoms and tiny electrons in the electron cloud.
To say there is nothing there is simillar to saying water has no taste. There is something there, though we have yet to observe or define it.
Rutherford, with his gold foil experiment.
0%. Outer space is filled by Maxwell's Aether with "free space Resistance" z= W/Q =375 Ohms, where W and Q are electromagnetic Charges. Planck's Constant h=QW.
Yes. In 1908, Rutherford conducted an experiment of shooting a beam of alpha particles through a sheet of tinfoil. Most of the alpha particles went straight through the foil, …which proves that there are empty spaces in atoms. And the rest of the particles that didn't go straight through the foil are deflected at acute angles, those particles are deflected by the positive nucleus in the center of the atoms.
Yes in fact Ernest Rutherford discovered that atoms contain mostly empty space, with his gold foil experiment. He discovered that the electrons are not randomly placed around… the nucleus. Read more: http://wiki.answers.com/What_scientist_said_atoms_contain_mostly_empty_space#ixzz17NE5I4gI
not exactly. it is mostly empty space- about 99.99...% but at the centre of the atomic structure, there is a nucleus which contains nucleons (protons and neutrons).… incredibly small electrons circulate around the nucleus, but their mass is negligible- about 1/2000 the mass of a proton. x
Actually this is true. The nucleus of an atom makes up a very small percentage of the atom (to be safe I am going to say less than five percent at largest.) The rest of the at…om is composed of the electron orbitals. Since there can only be so many electrons in a single orbital at any given time most of the space in the orbital is never filled. Thus a large majority of an atom is indeed empty space.
Yes, this was proven by the Geiger-Marsden experiment (also known as the gold foil experiment).
If the space is in outer space there can be no gas against which a terminal velocity can occur
What scientist demonstrated that the atom is mostly empty space with a small positively charged nucleus containing most of the mass of the atom?
What observations by Rutherford led to the hypothesis that atoms arre mostly empty space and that almost all of the mass of the atom is contained in an atomic nucleus?
most of the alpha particle pass through the gold foil without deviation and the mass of electron are very small
Anybody who knows much about atoms and is willing to ignore virtualparticles. The credit for actually discovering this should probably go toRutherford. (Or Rutherford, Geiger,… and Marsden ... Geiger andMarsden actually did the experiment in Rutherford's lab, andRutherford was the one who explained the results.)
