Question

Toppr Admin · Accepted Answer

Correct option is B- Both Assertion and Reason are correct but Reason is not the correct explanation for AssertionThe chemistry of the early actinoids is more complicated than the corresponding lanthanoids - due to the large number of oxidation states possible for these actinoids and their radioactive nature-

ReasonOuter electronic configuration of actinoids is $$(n - 2)f^{1 - 14} (n - 1)d^{0 - 1} ns^2$$.AssertionThe chemistry of the early actinoids is more complicated than the corresponding lanthanoids.

Reason
Outer electronic configuration of actinoids is $$(n - 2)f^{1 - 14} (n - 1)d^{0 - 1} ns^2$$.
Assertion
The chemistry of the early actinoids is more complicated than the corresponding lanthanoids.
