Can one see physically with our eyes the particles such as Electrons,protons,neutrons etc .?
We know that all matter in our world is composed of atoms. An atom consists of a nucleus surrounded by electrons. A nucleus contains protons and neutrons, which are made up of quarks. The electron and quarks are elementary particles which cannot be divided further. In addition to the elementary particles that constitute matter, there is another type of elementary particles that mediate the fundamental force between matter particles. For example, the electromagnetic force is mediated by photon, the gravity is mediated by graviton. You may have learned that the magnetic force is mediated by the magnetic field. Similarly, you can say that the electromagnetic force is mediated by the electromagnetic field. In quantum physics, a \”field\” can also be viewed (\”quantized\”) as a particle. The photon is the particle name of the electromagnetic field. The graviton is the particle name of the gravitational field.
