Question

Which of the following can be used to see atoms?
a) Scanning tunnelling Microscope
b) Compound Microscope
c) Stereo Microscope
d) Confocal Microscope

Answer 1

We have to know that the atom is the basic unit of the world. In science, initially said atoms are tiny particles. The compound is made up of molecules. The molecules are made on the atoms. The atom is made up of protons, electrons and neutrons. The protons, electrons and neutrons are considered microscopic particles in the world.

Complete answer:
We have to know that the scanning tunnelling Microscope is one of the microscopes used to see the atoms in the molecules based on the tunnelling of electrons. The tunnelling of electrons is mainly for visualisation of electrons in the microscope.
According to the above discussion we conclude, Scanning tunnelling Microscope is used to see atoms in molecules.
Hence,
Option A is the correct answer because scanning tunnelling microscopes are used to see atoms in molecules.
Option B is not the correct answer because compound Microscope is not used to see atoms in molecules.
Option C is not the correct answer because stereo Microscope is not used to see atoms in molecules.
Option D is not the correct answer because a confocal Microscope is not used to see atoms in molecules.

So, the correct answer is “Option A”.

Note:
We need to know that the scanning tunnelling Microscope is one of the microscopes used to see the atoms in the molecules. The short form of Scanning tunnelling Microscope is STM. Scanning tunnelling Microscope is also known as tunnelling Microscope. Quantum mechanics is the basic principle used in the Scanning tunnelling Microscope. It was invented by Gerd Binning and Heinrich Rhorer in the end of the nineteenth century.
