how come we cant see atoms but we can see electrons and proton which are smaller.?

Answer 1

The only way we "see" atoms, protons and electrons is from their effect on other things. Generally scientist use a computer to form the image of these particles or they can be seen by their effects on a cloud chamber or through the use of photon-multiplier tubes. To see images, artistic or computer renderings, of atoms you can go to the following site: http://www.almaden.ibm.com/vis/stm/hexagone.html#stm1

Answer 2

What do you mean by see? We can indirectly detect electrons and protons, but we can't see them visually. Interestingly nuclei of heavy atoms have been visulaised using electron microscopes.

Answer 3

Atoms have been photographed. See them on this website ==>http://www.andrewlost.com/atoms_molecules_k1.htm

Electrons, protons and other subatomic particles have never been seen directly, but in high-energy particle acclerators the tracks they make have been photographed. Check this website ==>http://www.physorg.com/news84730570.html
