The invention of the scanning tunneling microscope (STM) in 1981 by Gerd Binnig and Heinrich Rohrer, and the atomic force microscope (AFM) in 1986 by Christoph Gerber, Calvin Quate, and Gerd Binnig, were critical in enabling scientists to visualize individual atoms for the first time. These instruments use a sharp probe to scan the surface of a sample, detecting variations in atomic forces or electron tunneling currents to create images with atomic resolution.
Some inventions that have been developed using atoms include atomic clocks, nuclear reactors, and scanning tunneling microscopes. These inventions rely on the precise manipulation and understanding of atomic structures to function effectively.
Technology such as advanced microscopes and spectrometers allowed scientists to observe and analyze atomic structures and behaviors, leading to the development of atomic theory. For example, the invention of the electron microscope enabled scientists to observe individual atoms. Additionally, advancements in computational tools and simulations have allowed for further exploration and understanding of atomic properties and interactions.
Scientists can study the inner structure of an atom using various techniques such as X-ray crystallography, electron microscopy, and particle accelerators. These methods help to determine the arrangement of electrons in the atom's electron cloud and the position of the nucleus. By analyzing the interactions of particles with atoms, scientists can gain insights into their arrangement and behavior.
Early scientists speculated that the concept of atoms could explain the behavior of matter. The idea of atoms was proposed by ancient Greek philosophers such as Democritus around 400 BC, suggesting that matter is composed of indivisible particles. It wasn't until modern times that scientists were able to provide experimental evidence for the existence of atoms.
X-ray crystallography is a common experimental method that allows scientists to estimate atomic and ionic radii by measuring the distances between atoms in a crystal lattice. By analyzing the diffraction patterns produced by X-rays passing through a crystal, researchers can determine the spatial arrangement of atoms and thus their radii.
An electron microscope.
B. Scanning Tunneling
The good kind! :D
Yes. Using a Scanning Tunnelling Microscope (or some variant thereof), individual atoms can be mapped.
Scientists can look at individual atoms using powerful tools such as scanning tunneling microscopes or atomic force microscopes. These instruments use a fine probe to scan the surface of a material at the atomic level, providing detailed images of individual atoms.
A one-Angstrom microscope allows scientists to see individual atoms. At this scale, scientists can study the arrangement and behavior of atoms within materials, which is essential for understanding the properties and behavior of matter at the atomic level.

21 different kinds of atoms
They view atoms through an electron microscope.
Scientists use models to study atoms because atoms are too small to be seen with the naked eye. Models provide a visual representation of atoms that helps scientists understand their structure and behavior. By using models, scientists can make predictions and test hypotheses about atomic interactions.

"View" may not be exactly the right word. A Scanning Tunneling Microscope can be used to gather data that a computer can turn into an image, but they're not really "seeing" the individual atoms directly.
