Explanation:
The size of an atom is extremely small, in the range of nanometers. Therefore, conventional instruments like Vernier calliper, screw gauge, or optical microscope cannot be used to measure the size of an atom. The most suitable instrument for measuring the size of an atom is the electron microscope.
Electron Microscope:
An electron microscope uses a beam of electrons instead of light to magnify the sample. It has much higher magnification and resolution power than an optical microscope. The resolution of an electron microscope is in the range of picometers, which is much smaller than the size of an atom.
Types of Electron Microscope:
There are two types of electron microscopes:
1. Transmission Electron Microscope (TEM): A TEM is used to study the internal structure of the sample. In a TEM, the electron beam passes through the sample, and the transmitted electrons are detected to form an image.
2. Scanning Electron Microscope (SEM): A SEM is used to study the surface structure of the sample. In a SEM, the electron beam scans the surface of the sample, and the backscattered electrons are detected to form an image.
Advantages of Electron Microscope:
1. High magnification and resolution
2. Can study samples at atomic level
3. Can study internal and surface structure of the sample
4. Can study biological and non-biological samples
Therefore, an electron microscope is the most suitable instrument for measuring the size of an atom.
