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.
Yes, you can see one with an electronic microscope. Not sure who the first person to see one was. Yes, you can see one with an electronic microscope. Not sure who the first person to see one was.
Actually, the thought about electricity came before atoms. In about 600 B.C. Thales of Miletus discovered that a piece of amber, after rubbing it with fur, attracts bits of hair and feathers and other light objects. He suggested that this mysterious force came from the amber. Thales, however, did not connect this force with any atomic particle.
Not until around 460 B.C., did a Greek philosopher, Democritus, develop the idea of atoms. He asked this question: If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can break it no further? Democritus thought that it ended at some point, a smallest possible bit of matter. He called these basic matter particles, atoms.
Unfortunately, the atomic ideas of Democritus had no lasting effects on other Greek philosophers, including Aristotle. In fact, Aristotle dismissed the atomic idea as worthless. People considered Aristotle's opinions very important and if Aristotle thought the atomic idea had no merit, then most other people thought the same also. (Primates have great mimicking ability.)
For more than 2000 years nobody did anything to continue the explorations that the Greeks had started into the nature of matter. Not until the early 1800's did people begin again to question the structure of matter.
In the 1800's an English chemist, John Dalton performed experiments with various chemicals that showed that matter, indeed, seem to consist of elementary lumpy particles (atoms). Although he did not know about their structure, he knew that the evidence pointed to something fundamental.

Not according to any source I could find. We know they exist due to indirect evidence only.
No. Many scientists will claim they have, or claim they are showing your pictures of atoms, but no human has ever actually seen atoms.
No nobody has ever seen an atom or atoms, though many people/scientists claim they have, NOBODY HAS EVER SEEN AN ATOM!
Dmitri Mendeleev
yes it has
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.
Einstein proved the existence of them but it was Newton who made the theory that everything is made of atoms.
Ernest Rutherford proved it with his famous gold foil experiment.
Yes: Atoms of krypton almost always do exist independently of chemical bonding to any other atoms.
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.

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.
* He proved nothing, but he did say God made the earth.
No one has proven that God does not exist.
