Q. Consider the following statements regarding the Neutrino:
1. The neutrino is a tiny elementary particle which is not part of the atom.
2. Neutrino has a very tiny mass and with no electrical charge.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C

Proton, neutron, and electron are tiny particles that make up atoms.  

  • The neutrino is also a tiny elementary particle, but it is not part of the atom. Such particles are also found to exist in nature. 
  • Neutrino has a very tiny mass and no charge. It interacts very weakly with other matter particles.  
  • So weakly that every second trillion of neutrinos fall on us and pass through our bodies unnoticed. 
  • Neutrinos come from the sun (solar neutrinos) and other stars, cosmic rays that come from beyond the solar system, and from the Big Bang from which our Universe originated.  
  • They can also be produced in the lab.
