What is a scanning tunneling microscope?
(STM) uses an electron beam not only to image things, getting resolution at the atomic level, but actually manipulate them too -a powerful technique for viewing surfaces at an atomic level. -invented by Gerd Binnig and Heinrich Rohrer -based on the concept of quantum tunneling
How can scientist observe atoms?
By using a telliscope
Why is it not possible to see an atom with naked eyes?
Atoms are incredibly small, millions of times smaller than the wavelength of visible light. This makes them impossible to see with the naked eye as they are beyond the limit of human visual resolution. Specialized instruments like scanning tunneling microscopes are needed to observe atoms.
Why a microscope is necessary in order to observe brownian motion?
A microscope is necessary to observe Brownian motion because the movement of particles is very small and needs to be magnified in order to be visible to the human eye. The microscope allows us to see the random motion of the particles as they collide with each other and move in a liquid or gas. Without a microscope, the individual particle movements would be too small to detect.
What instrument is used to see a magnified view of a very small objects?
A microscope is used to see a magnified view of very small objects. It enables scientists to observe structures and details that are not visible to the naked eye. There are different types of microscopes, such as optical, electron, and scanning probe microscopes, each with its own set of features and capabilities.
What are the tools that scientists used to observe atoms?
They could use an electron microscope or an STM (scanning tunneling microscope)

What type of microscope is used to show atoms?
The scanning tunneling microscope has a small probe which actually more like "feels" the size of the atoms and reads this out on a computer screen. The probe can pick up individual atoms. IBM used a STM years ago to spell I B M with uranium atoms and took a picture of it. But one does not actually directly "see" the atoms.
Which microscope is used to observe small surface detail?
Scanning electron microscope.
Can scientists observe single atoms?
Yes. Using a Scanning Tunnelling Microscope (or some variant thereof), individual atoms can be mapped.
What type of microscope allows you to observe single atoms?
scanning probe
Which type of microscope can observe non-living cells?
A tunneling electron microscope cannot image live specimens.
Which type of microscope would be used to observe structures on the surface of an individual cell?
A scanning electron microscope (SEM) would be used to observe structures on the surface of an individual cell. SEM uses a focused beam of electrons to scan the surface of a sample, producing high-resolution images of the surface features of the cell.
Are Scanning microscopes used to observe individual atoms?
No. Scanning Electron Microscopes (SEM) use electrons to view microsopic details down to the granular structure of material. Since it uses electrons, it could not detail anything the size of an Atom.
Which instrument do scientists use to observe DNA?
Usually, a scanning electron microscope is used to observe atoms.
What kind of microscope would you use to observe the surface features of a baterium?
You would use a scanning electron microscope (SEM) to observe the surface features of a bacterium. SEM provides high-resolution images of the specimen's surface by scanning it with a focused beam of electrons. This allows for detailed visualization of the bacterium's structure at a nanoscale level.
What type of microscope you used to observe the pores of skin?
A scanning electron microscope (SEM) is often used to observe pores of the skin due to its high resolution and magnification capabilities. This type of microscope allows for detailed imaging of the surface features of the skin at a micro or nanoscale level.
