Worked Example: Identical particles For CSIR NET
Consider a system of two electrons in a hydrogen atom. In quantum mechanics, electrons are considered identical particle, meaning they have the same intrinsic properties, such as mass, charge, and spin.
A question arises: Which of the following statements is true about the electrons? The options are: (a) The electrons are distinguishable and have unique properties; (b) The electrons are indistinguishable and have the same properties; (c) The electrons are identical but can be distinguished by their position.
The correct answer can be deduced by understanding the concept of identical particle. Identical particles are characterized by their exchange symmetry, which implies that swapping the positions of the particles does not result in a distinguishable state.
The statement in option (a) that “The electrons are distinguishable and have unique properties” is incorrect. Instead, the electrons in a hydrogen atom are identical and indistinguishable. Therefore, the correct answer is option (b).
