Transition Metals and Colored Complexes

A typical transition metal has more than one possible oxidation state because it has a partially filled d orbital. When transition metals bond to one more neutral or negatively charged nonmetal species (ligands), they form what are called transition metal complexes

Answer 2

Answer:

Yes, the colored precipitates all contain transition-metal ions with partially filled d orbitals.

Explanation:

• The solution will be colored if it contains transition-metal ions with partially filled d orbitals.
• It is well known that transition metals contain partially filled d orbitals. Between-group 2 and group 13 in the main group, the transition metals are located in the middle of the periodic table.
• They have colored solutions as a result of the d-d transitions that take place in transition elements with partially filled d orbitals. The existence of a transition metal ion may therefore be shown in the observation by a colored solution.

So,  Yes the colored precipitates all contain transition-metal ions with partially filled d orbitals.
