Question

Quizplus · Accepted Answer

The atomic force microscope (AFM) is the only instrument listed that is capable of imaging individual atoms on a surface. AFM uses a small cantilever with a sharp tip that moves over the surface of the sample and interacts with the atoms, producing a three-dimensional image of the surface. The other microscopes listed are not capable of imaging individual atoms.
