  It’s to do with something called the ‘diffraction limit’. What that means is that you cannot use light to take a picture of something that is smaller than the wavelength of light. Since the wavelength of visible light is between 400 and 700nm (slightly less than 1/1000000 of a metre), it’s too big to be able to take a picture of an atom, which is about 0.1nm in diameter.
