How electron microscopy and scanning tunneling microscopes how contributed to the understanding of atoms?
Electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

Explain how electron microscopy and scanning tunneling microscopes have contributed to the understanding of atoms?
Electron microscopy uses a focused beam of electrons to create detailed images of atomic structures, allowing scientists to see atoms and their arrangement in materials. Scanning tunneling microscopes use a fine tip to measure the electrons flowing between the tip and the surface of a material, providing atomic-scale resolution and enabling scientists to manipulate atoms. Both techniques have revolutionized our understanding of atoms by allowing direct observation and manipulation at the atomic level.

Can you see atoms with a microscopes?
Traditional light microscopes cannot see individual atoms due to their limited resolution, typically on the scale of hundreds of nanometers. Specialized techniques such as scanning tunneling microscopy and atomic force microscopy have been developed to image individual atoms by scanning a sharp probe tip over a surface at extremely close distances.
What are the tools that scientists used to observe atoms?
They could use an electron microscope or an STM (scanning tunneling microscope)
Is there another example of a microscope other than the light and electron microscope?
Yes, there are different types of microscopes, such as the scanning probe microscope, which includes atomic force microscopy and scanning tunneling microscopy. These microscopes operate by scanning through a surface at a nanoscale level to create images with high resolution.
What are the advantages of scanning tunneling microscopy?
Scanning tunnel microscopy has many advantages. It captures much more detail than other microscopes for better understanding of specimen. They can be used in various mediums like ultra high vacuum, air, water etc. They can work in a range of temperatures.

What replaces the electron and field ion microscope?
Advanced microscopy techniques such as scanning tunneling microscopy (STM) and atomic force microscopy (AFM) are now commonly used in place of electron and field ion microscopes. These techniques offer high-resolution imaging of surfaces at the atomic and molecular level without the need for a vacuum environment like in traditional electron microscopy. Additionally, techniques like correlative microscopy, combining different imaging modalities, are also gaining popularity for studying biological samples in situ.
What do you view atoms with?
You can view an atom with a scanning- tunneling microscope and a atomic force microscopes.
You can see atoms using a scanning tunneling microscope?
Yes, scanning tunneling microscopes (STMs) can be used to see individual atoms on a surface. By measuring the current that flows between a sharp tip and the sample surface, STMs can create atomic-scale images with high resolution. This technology has been crucial in advancing our understanding of atomic structures and phenomena on the nanoscale.
What are the different types of microscopes and their purposes?
There are reflective microscopes (similar in design to a telescope), and transmission microscopes where the objective is on the other sample and used for looking at slides. There are phase-contrast microscope, electron microscopes and scanning tunneling microscope.
What microscopes can enlarge images up to 100000 times or more?
An electron microscope can enlarge images up to 10,000,000 times (107x).Other types of microscopes that can achieve over 105 magnification include scanning probe microscopes, such as atomic force microscopes, electrostatic force microscopes, magnetic force microscopes, scanning tunneling microscopes, and piezo force microscopes.
