Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom.
A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
That atoms have a positively charged nucleus.
Rutherford found that atoms have a nucleus
Bohr's contribution to chemistry and physics regarding atoms was a theory on the atomic structure refining rutherfords model. Atoms were already shown to exist by others. Dalton is perhaps the most influential of the early pioneers.
This is the Rutherford model.
Ernest Rutherford's famous "gold foil" experiment changed the way we though of atomic structure. His demonstration proved that atoms have a small, dense nucleus which contains protons and neutrons. The electrons were shown to be outside the nucleus. Prior to this, we thought atoms had a consistent structure throughout, like soup or pudding.
Rutherfords Model is Rutherfords Model... thats it, its just a model.. go look it up on google images im sure you will figure it out by then.
The conclusion was that an atom has a nucleus (center) with a positive charge.
The most surprising fact about Rutherford's experiment is that some of the atoms bounced backwards while others scattered.
Look down at the link "Atomic structure of silicon atoms". There you will find the atomic structure of silicon atoms.
As the atoms of the heat/air pass into the atoms of the ice cubes, the ice cube's atoms start to lose its structure. So the atoms move into a liquid structure, or melt.
potassium
Yes - it showed that atoms have a small but massive nucleus, with a positive charge - i.e., what we today know as protons. (Neutrons were discovered later.)
