Question

Assertion :Bohr's atomic model cannot be used to explain multiple electron species. Reason: It does not take inter-electronic interactions into account.
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
  3. Assertion is correct but Reason is incorrect.
  4. Both Assertion and Reason are incorrect.

A
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
B
Both Assertion and Reason are incorrect.
C
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
D
Assertion is correct but Reason is incorrect.
Solution
Verified by Toppr

Bohr's atomic model is valid only for single electron species because it does not consider forces due to inter-electronic attractions.
