COMEDK · Chemistry · 23. d and f Block Elements
Pick out the correct option
Assertion(A): Mercury is not considered as a transition element
Reason (R): Mercury is a liquid
- A A is false but R is true
- B Both A and R are true but R is the correct explanation of A
- C Both A and R are true, R is not the correct explanation of A
- D A is true but R is false
Answer & Solution
Correct Answer
(C) Both A and R are true, R is not the correct explanation of A
Step-by-step Solution
Detailed explanation
Assertion (A) is true because transition elements are defined as elements having incompletely filled d-orbitals in their ground state or in any of their common oxidation states. Mercury (Hg) has a completely filled d-orbital (\(5d^{10}\)) in its ground state as well as in its…
