Answer 1

You don’t. TEM and SEM are used to view very small specimens, the general procedure varies depending on what you’re looking for, for example in cell biology, certain proteins of interest are looked at using gold attached to antibodies, the gold balls reflect the beam of electrons creating very dark regions, which can be seen in imaging. Electrons themselves however, cannot really every be seen, we can only predict roughly where they are, which represent solutions to the Schrödinger equation.
