Why are transition metals colored?
Transition metal compounds are often highly colored, due to d to d electron transitions. They often form paramagnetic compounds because of their unpaired d electrons. In their elemental form, they often act as catalysts.
What format did the original periodic table use?
The original periodic table featured periodicity in a simple 8-column format. In other words unlike the current periodic table that recognizes the increasing length of periods as atomic number increases, (2, 8, 18, 32 etc.) the original table attempted to squeeze all the elements into an 8-column format. In order to do this Mendeleev and other pioneers of the periodic table were obliged to remove certain elements from the main body of the table and had to create a special group VIII which featured “transition elements” including Fe, Co, Ni, Ru, Rh, Pd, Os, In, Pt.

Why are transition metals called transition metals?
These elements are called " transition metals " because the electrons of their atoms make the transition to filling the d subshell or d sublevel orbital. Thus, the transition metals are also known as the d-block elements. Here is a list of elements that are considered to be transition metals or transition elements.
Which transition metals have high melting points?
The transition metals, as a group, have high melting points. The exception is mercury, which is a liquid at room temperature. By extension, these elements also have high boiling points. Their d orbitals become progressively filled as you move from left to right across the periodic table.
Why do transition metals have colored complexes?
Transition metals form colored complexes, so their compounds and solutions may be colorful. The complexes split the d orbital into two energy sublevels so that they absorb specific wavelengths of light. Because of the different oxidation states, it's possible for one element to produce complexes and solutions in a wide range of colors.

Why Are They So Colorful?
- It is because of their unfilled d orbitals, and something called “d to d electronic transitions”. When a transition metal forms an ion, its electrons can absorb light and move between d orbitals. The d orbitals are normally degenerate, meaning they are all at the same energy level. But when a transition metal forms a complex with a ligand, such as H2O or NH3, the d orbitals develop diffe…
