Nobody has ever seen an atom directly, but the first people to image an atom using scanning tunneling microscopy were at IBM Almaden. While this method doesn't allow you "see" an atom, it does allow you to make a picture which shows the shape and size of atoms.
See the Related Question link and look for the link to some of the pictures of atoms.
The scientist that proved that atoms exist was Democritus. He couldn't prove it or test it though. But today, scientists are able to prove Democritus' idea and learn more about the atom everyday.
Ernest Rutherford proved it with his famous gold foil experiment.
Smashing atoms in an accelerator proves that atoms are made of smaller particles which themselves are made of smaller particles. An accelerator is needed to reach the minimum energy level required to do this though, atoms don't just simply disintegrate themselves, unless in a fission nuclear reactor. Einstein proved that atoms exist when he studied Brownian motion, which is what happens when you put grains of pollen in water. The move around without any apparent objected causing it. Einstein proved that the grains moved because atoms were causing that motion.
Yes: Atoms of krypton almost always do exist independently of chemical bonding to any other atoms.

John Dalton is considered the scientist who developed the modern atomic theory, providing evidence for the existence of atoms through his experimentation with gases.

we do not know, scientist have not proved that they exist yet. sorry. Assuming that they did exist they would weigh 1 horn more then a horse.

Schwarzschild black holes. Named after the scientist who proved mathematically black holes can exist.
The English scientist who first offered strong evidence that atoms exist was John Dalton. He proposed his atomic theory in the early 19th century, which laid the foundation for modern atomic theory and our understanding of the nature of matter.
* He proved nothing, but he did say God made the earth.

No-one has ever proved that Yeti exist, so the answer has to be NO.
