 We cannot directly see atoms with a regular microscope. Light has a wavelength of between 4,000Å and 7,000Å which is about 1000 times the diameter of an atom. Because the wavelength of light is so long it has almost no interaction with the atom. The center of an Atom can be "viewed" and the positions of the electron cloud around an atom can be determined by using an X-ray, (neutron, or electron) beam (which have much smaller wavelengths than light) in such techniques as

-Use the rubber band to attach the steel wool to the eraser end of the pencil.  The pencil should be short enough that it can fit inside the glass without sticking out the top.  Fill the glass halfway with water, and place the pencil in the glass with the wad of steel wool at the bottom.  Place a bowl upside-down over the top of the glass, and carefully turn the glass and the bowl over so that the glass is upside-down and the bowl is right-side-up.  Add some water to the bowl and mark the water level on the side of the glass.  Place the apparatus some place where it will not be disturbed.  After a few days, check the steel wool - it should be rusty.

-As the steel wool rusts, it uses up oxygen trapped in the glass.  This reduces the volume of air inside the glass, and the atmospheric pressure outside the glass will compensate by pushing down on the water inside the bowl.  This will in turn push the water in the glass higher.  Verify by comparing the current water level to the level marked at the beginning of the experiment.
