gradually decreases from left to right

gradually increases from left to right

does not change due to presence in the same period

Sc 3+ solution in the presence of water is colorless. Why?

There is no electrons to be excited

Presence of ligands cause the splitting of 3d orbital.

There is no splitting of 3d orbitals

Energy level is too high for electron to reach

Zn 2+ solution in the presence of water is colorless. Why?

3d orbitals are fully filled and no electrons can be excited

Presence of ligands cause the splitting of 3d orbital.

There is no splitting of 3d orbitals

There is no electrons to be excited
