प्रश्न
Assertion (A) : Copper is a non-transition element.
Reason (R) : Copper has completely filled d-orbitals in its ground state.
विकल्प
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false, but (R) is true.
उत्तर
(A) is false, but (R) is true.
Explanation:
Copper is a transition metal due to the presence of incompletely filled d-orbital in its common oxidation state Cu+2 (3d9) while in its ground state the electronic configuration of Copper is (3d104s1).
