NettetThe thing is, atoms are very, very small, but they still have a finite size. A hydrogen atom, for example, is about 0.1 nanometers, and a caesium atom is around 0.3nm. The … NettetTo see anything smaller than 500 nm, you will need an electron microscope. Electron microscopes shoot a high-voltage beam of electrons onto or through an object, which deflects and absorbs some of the electrons. Resolution is still limited by the wavelength of the electron beam, but this wavelength is much smaller than that of visible light.
