Directions: These questions consist of two statements, each printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses.


Assertion : Electrons in the atom are held due to Coulomb forces.


Reason : The atom is stable only because the centripetal force due to Coulomb’s law is balanced by the centrifugal force.

  • a)
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

  • b)
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

  • c)
    If the Assertion is correct but Reason is incorrect.

  • d)
    If both the Assertion and Reason are incorrect.

Correct answer is option 'C'. Can you explain this answer?

Correct option is C. If the Assertion is correct but Reason is incorrect.


Explanation: The Assertion is correct. Electrons in an atom are indeed held in their positions due to the Coulomb force, which is the electric force between the positively charged nucleus and the negatively charged electrons.


However, the Reason is incorrect. The stability of an atom is not due to a balance of centripetal and centrifugal forces. The classical concept of centrifugal force balancing the Coulombic centripetal force, as would be the case in a planetary model of the atom, is not valid in quantum mechanics. In quantum mechanics, electrons occupy orbitals around the nucleus without necessarily revolving in the classical sense, and their positions and energies are described by wave functions. The stability of the atom is due to the quantum mechanical principles, including the Heisenberg Uncertainty Principle and the Pauli Exclusion Principle, not a balance of classical forces.
