Part 1
1. What are Transition Metals?
2.Explain what specifically happens to transition metals that results in solutions that give off distinct colors.
3. Show an example of a specific transition metal solution, including the oxidation state of the transition metal, and the color of the solution, and the complex ion that the transition metal forms in that solution if applicable.
Part 2:
1. What are complex ions?
2. Explain how complex ions are formed, and how to name a complex ion.
3. Show an example of a specific complex ion including EITHER it's formula or its name. Ask your fellow classmates to give either the missing name or formula using the rules for naming complex ions to explain how the name or formula was determined.
Explanation / Answer
1. Transition metal ; the elements in which have incomplete d-orbitals , either in eiemeeleme state or in most common oxidation state , are called transition elements .
i.e (n-1) d ^1-9 ns^0-2 are transition elements electronic configuration .
2 . Transition metals have incomplete d-orbitals , thus have unpaired electrons . These unpaired electrons absorb energy and show transition from ground state to excited state and again re-emit energy from excited to ground state in form of radiation of a particular color .
Thus presence of unpaired electrons is the base for the color of transition elements .
3. FeSO4 solution , in this Fe is transition metal .
Fe is in +2 oxidation state having configuration 3d^6 , thus having 4 unpaired e-s in d-orbital .
The color of the solution is blue .
The complex formed in aqueous solution is FeSO4.5H2O .
