What percent of the atom is free space empty of mass?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

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.

Are atoms empty space?

They are mostly empty space apart from the protons and neutrons in the middle of the atoms and tiny electrons in the electron cloud.

What percent of outer space is empty?

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.

Do atoms have empty space?

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,

Do atoms contain empty space?

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

Is an atom a empty space?

  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).

Most of the atom is empty space?

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

Who said most of an atom is an empty space?

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,
