Can we see atoms or other atomic stuff like electrons and protons, etc.? If not, how can we know they exist and how they behave?

I'd flip that over and say that in experimental sciences, very little (close to nothing) is based on what can be seen with our eyes.ZapperZ said:The existence of atoms involves MORE than just what you can (or cannot) see with your eyes!

Emilyjoint said:probably better to ask can we detect atoms rather that can we see.
you do not need to see with your eyes to know something exists.

thankyou -- amazing what they can achieve these days

Hi guys - I don't mean to "hit and run" as you call it and I apologize if that is the traditional forum etiquette here to return to a thread to post afterwards.

The thing to do, if you really don't know much about the subject you post a question about, you should make that clear. If you are already half way there then I feel you should word the question appropriately (say, with some Maths). It's all too easy to give an answer that's way below or above what the OP wants and that can frustrate everyone.
I have read some excellent questions that start off "I am doing AS Physics and I have just come across a problem with the Photoelectric effect . . . . ." We all know where we stand then and the OP will probably have got the answer after a couple of responses.
No, we cannot see atoms with our eyes because atoms are much smaller than the wavelength of visible light, which is what our eyes can detect.
Scientists use a variety of techniques such as microscopy, spectroscopy, and particle accelerators to indirectly observe and study atoms. These techniques provide evidence for the existence of atoms through their behavior and interactions with other particles.
It is currently not possible to directly see an individual atom, but scientists have developed advanced microscopes that can capture images of groups of atoms, known as scanning tunneling microscopes and atomic force microscopes. However, these microscopes still use indirect methods to detect the presence of atoms.
Scientists have developed models and theories based on experimental evidence to understand the structure and behavior of atoms. The most widely accepted model is the quantum mechanical model, which describes atoms as having a nucleus made up of protons and neutrons surrounded by electrons in energy levels.
Yes, scientists have developed techniques to manipulate individual atoms using specialized tools such as atomic force microscopes and lasers. This has led to advancements in fields such as nanotechnology and materials science.
