Directions : In the following questions, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.
Assertion (A): Bohr model is not applicable for multi-electron models.
Reason (R): Bohr model cannot account for sublevel (s, p, d, f) orbitals and electron spin.
  • a)
    Both A and R are true and R is the correct explanation of A
  • b)
    Both A and R are true but R is NOT the correct explanation of A
  • c)
    A is true but R is false
  • d)
    A is false and R is true
Correct answer is option 'A'. Can you explain this answer?

Bohr model works well for H and He+ having one electron only. But it does not work for multi-electron atoms, since it cannot account for sublevel (s, p, d, f) orbitals and electron spin. So, assertion and reason both are true and reason explains the assertion.

Directions : In the following questions, A statement of Assertion (A)...
Explanation:

Bohr model is not applicable for multi-electron models because it was developed for hydrogen atom, which has only one electron. As we move to elements with more than one electron, the Bohr model fails to accurately predict the behavior of these atoms.
However, the reason for this limitation is that Bohr model cannot account for sublevel (s, p, d, f) orbitals and electron spin. These concepts are crucial in understanding the behavior of multi-electron atoms.
Therefore, both the Assertion and Reason are true, and the Reason provides a correct explanation for why the Bohr model is not applicable for multi-electron models.
