Question

transition metals form coloured compounds it is true or false​

Answer 1

The reason why transition metal in particular are colorful is because they have unfilled or either half filled d orbitals. There is Crystal field theory which explains the splitting of the d orbital, which splits the d orbital to a higher and lower orbital.

Answer 2

Answer:

True

Explanation:

When visible light(i.e.light under visible spectrum) falls on a transition metal compound or ion, the unpaired electrons present in the lower energy d-orbital get promoted to high energy d-orbitals, called d-d transition, due to the absorption of visible light. Therefore, transmitted light shows some colour complementary to the absorbed colour.
