Subatomic Particles:
from Electrons to Quarks
Rakesh Mohan Hallen
Electrons
• Can an electron reverse its spin from +1/2 to -1/2 or vice versa?
• Why is a magnetic field created by the flow of electrons?
• How was an electron born? Why does it move around the nucleus?
• Is an electron divisible into other particles?
• From where do the electrons get the energy to revolve around the nucleus?
• How is it possible that though the drift velocity of the electron is 0.1cm/s to 1cm/s when the light is switched on the bulb starts glowing immediately.
• Is there any way to distinguish between two electrons not located in the same atom but having equal energy and parallel spin?
• Who was the first person to see the electron with his naked eyes?

‘Electron' like ‘atom' is a concept in science, which helps us to explain a vast array of natural phenomena. As was mentioned last month the concept of electron was conceived by Stoney and J. J. Thomson provided the......
