Has anyone ever seen an Atom or subatomic particles?

You can't see an atom, never mind subatomic particles, in the same way as you would looking down a microscope. The wavelength of light is far too large compared to the size of an atom. However, using an electron microscope, you can get images like this of silicon nitride, where individual atoms of the molecule can be made out.

However, this is based on electrons hitting the atom and a computer analysing the results, rather than light waves. Atoms are simply too small to be seen directly. http://www.iatia.com.au/technology/sampl… If you get atoms and smash them together at high speeds, then you can analyse the particles within the atom.

You can study the electrical charge of electrons and protons by performing experiments such as Rutherford's classic nineteenth century experiments where he proved that an atom must have a negatively charged outer shell and a positively charged nucleus (see source) ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
