Grammar nazis unite

Is there anything grammatically wrong with the following sentences? If so, how do I fix them.

a) An uncharged object contains a large number of atoms, each of them normally contains an equal number of electron sna dprotons, but with some electrons temporarily free from atoms.

b) The scientific world has believed the discovery of radio activity brought science a step nearer to the understanding of atomic structure.

c) As the flywheel turns all the points on, they move in concentric circles.

In the first sentence, what does "each" refer to (atoms or uncharged objects)? If you are referring to atoms I would replace "each of them" with "which". Repetition of the same verb should be avoided: "contain". The last clause also needs work: "however, a (considerable/significant/small = "xxxx" - depending on the facts) number of electrons are temporarily separated from the atoms"

a) Uncharged objects are made up of a large number of atoms, which normally contain an equal number of electron and protons; however, in such objects, a xxxx number of electrons are temporarily separated from the atoms.

The second sentence:

As the scientific community affirms, our understanding of atomic structure has been greatly improved as a result of the discovery of radioactivity.

Third sentence: no idea.

Sorry I can't be of further help and bear in mind that I looked at grammar rather than content.

As a flywheel turns, all the points on it move in concentric circles.
