Explain how electron microscopy and scanning tunneling microscopes have contributed to the understanding of atoms.

Electron microscopy and scanning tunneling microscopes contributed to the understanding of atoms in understanding atomic structure.

The electron microscope has magnifications of about 100,000x.

This helped the scientists to have accurate image groupings of the atoms. Scanning tunnel microscope helped scientists to have the images of groups of atoms.
