First of all atoms are invisible we will never see them okay. But you can use a electric microscope to observe and study them. Sadly they are huge and expensive
They view atoms through an electron microscope.
"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.
A microscope.
You can view an atom with a scanning- tunneling microscope and a atomic force microscopes.
A scanning tunneling microscope (STM) or an atomic force microscope (AFM) can be used to view single atoms. These instruments use a fine probe to scan the surface of a sample and create images with atomic resolution.
An electron microscope.
B. Scanning Tunneling
microscope
The good kind! :D
D. Set up a microscope so that visitors can view atoms. That's the only way you could view atom
An electron microscope is typically used to view organelles, as it provides a higher resolution and can visualize smaller structures compared to a light microscope. Transmission electron microscopes (TEM) are often used to view organelles at high magnifications.
A scanning probe microscope can provide a three-dimensional image of atoms or molecules on the surface of an object.
