Question

can atoms be seen with a microscope

Answer 1

yes atoms can seen in microscope but it cannot divide because it is so small

Answer 2

Typical atomic sizes are of the order of angstroms ([math]10^{-10} m[/math]). Some of the cutting edge electron microscopes can resolve features as small as 1 angstrom. So it is possible to see atoms under an electron microscope. For example, the below image [1] shows a gold nanoparticle. Each of those little bumps is an atom with radius about 1.6 angstrom.
