Question
Chemistry Question on d block elements
The colour of transition metal ions is due to presence of unpaired electron transitions in available empty electron in
A
d− orbitals
B
p− orbitals
C
s− orbitals
D
s and p-orbitals
Answer
d− orbitals
Explanation
Solution
The colour of transition metal ions arises from the excitation of unpaired electrons from the d-orbital of lower energy to the d-orbital of higher energy. This is for the reason that transition metal ions have the property to absorb certain radiations from the visible region and exhibit the complementary colour.
