Theoretical and experimental studies indicate that, with a high-resolution scanning electron microscope, it is now possible to obtain pictures of a single heavy atom resting on a thin carbon substrate. 
Fifty years of seeing atoms
Beyond imaging atoms, clusters, and defects on a surface, today’s microscopes can distinguish elements, monitor their diffusion and redistribution near the surface, and even create designer
Ultrathin Carbon Support Films for Electron Microscopy
Carbon support films only 4 to 6 angstroms thick have been made for use in electron microscopy. The determination of their thickness is based on geometrical calculation, electron scattering
The Tunneling Microscope: A New Look at the Atomic World
A new instrument called the tunneling microscope has recently been developed that is capable of generating real-space images of surfaces showing atomic structure. These images offer a new view of
Image of a Sulfur Atom
TLDR
Two-dimensional signal averaging has been applied to dark field electron micrographs of molecules of 2,3,4,5-tetraacetoxymercurithiophene and in the composite image, resulting from photographic superposition of 64 individual images, the sulfur atom in the molecule is clearly revealed.

TLDR
Several representative examples are chosen to illustrate the possibilities for atomic-resolution imaging of materials, and perspectives and outlook for the technique are briefly discussed.
Electron Energy Loss Spectroscopy And Annular Dark Field Imaging At A Nanometer Resolution In A Scanning Transmission Electron Microscope
The basics of electron energy loss spectroscopy (EELS) performed in the context of a scanning transmission electron microscope are described. This includes instrumentation, information contained in
Imaging the Rhodium Atom with a Conventional High Resolution Electron Microscope
THE ability of microscopes to make single atoms of metals visible has been reported by Muller1 and more recently by Crewe et al.2. Muller has been working with the direct imaging method of field-ion
