is this possible to see ELECTRON,PROTON AND NEUTRON, BY ANY INSTRUMENT.?

Question

i think this is impossible

Answer 1

Seeing is a funny word when it comes to small things. You can see their tracks in bubble chambers. That's like seeing an airplane's contrail, but not the plane itself. Whole atoms can be imaged directly with scanning tunneling microscopes, but that uses electron current in place of light.

Answer 2

It is quite possible. Electron microscopes "see" atomic size objects by using diffraction of electrons at 100keV-a few MeV energy. While the waves used to make the optical image are not photons in visible light, the basic principles are the same.

Protons and neutrons are another three orders of magnitude smaller than atoms, so they require an "electron microscope" with even higher energy in the GeV range. That is exactly what accelerators do! Admittedly, the "imaging problem" there is A LOT harder because we can "hit" the same proton or neutron only once and have to reconstruct "the image" from many different snapshots. What physicists do when they measure the parton functions (the distribution of quarks and gluons) with particle physics experiment essentially results in an image of how these particles are bound inside the proton and neutron.

This paper has reconstructed "pictures":

Hope this helps.

Answer 3

At such small scales, it is impossible to "see" these objects with visible light. Instead, we must infer their position using other methods, such as scanning electron microscopes. This allows for the detection of the two larger objects, the proton and neutron, but a discrete electron can never actually be observed according to quantum mechanics. It does, however, have a probability function representing how likely it is to be at a given position at a given time, hence the 'electron cloud' model in chemistry.

See the attached link for a SEM image of the IBM logo made with 35 Zinc atoms.

Answer 4

no it is not possible because for us to see any object it must be bigger than the wavelength of light atleast.......the wavelength of light is of the order 10 to the power -9 ......and the size of an electron is of the order 10 to the power -10 or it is 10 times smaller so instead of light falling on it it'll justt pass over it so no light will be reflected from it and hence we cant see....the only form of radiation we can use is the gamma radiation but it is too energetic to see with our eyes so we cant but if we use gamma radiations and project it on some phophorescent scree maybe we can detect it ....and also according to quantum physics the electron moves so fast the we cant see it in one place so we can observe it more as a cloud...or a number of places it can be

Answer 5

yes of course. Till date there is no practical method to see an electron, proton, etc.

Answer 6

How could think like that. Yes , we can see them by using "electron microscope".

Answer 7

They are too small to see.
