This is the modern atom model.
Electrons are in constant motion around the nucleus, protons and neutrons jiggle within the nucleus, and quarks
jiggle within the protons and neutrons.
This picture is quite distorted. If we drew the atom to scale and made
protons and neutrons a centimeter in diameter, then
the electrons and quarks would be less than the diameter of a hair and
the entire atom's diameter would be greater than the length of
thirty football fields! 99.999999999999% of an atom's volume is just empty space!
