Difference Between Titanium and Platinum

Titanium vs Platinum

Both titanium and platinum are d block elements. They are commonly known as transition metals. Like most of the transition metals, these also have the ability to form compounds with several oxidation states, and can form complexes with various ligands. Both the metals are very expensive, which has limited their usages.


Titanium is the element with the atomic number 22 and the symbol Ti. It is a d block element and present in the 4th period of the periodic table. The electron configuration of Ti is 1s2 2s2 2p6 3s2 3p6 4s2 3d2. Ti mostly forms compounds with +4 oxidation state. But it can also have +3 oxidation states. Atomic mass of Ti is about 48 g mol-1. Ti is a transition metal with a shining silvery color. It is strong but has low density, also corrosion resistant and durable. It has a higher melting point of 1668 oC. Titanium is paramagnetic and has low electrical and thermal conductivities. Availability of pure Ti is rare, since it is reactive with oxygen. The formed titanium dioxide layer acts as a protective layer on Ti and prevents it from corrosion. Titanium dioxide is very useful in paper, paint and plastic manufacturing industries. Though Ti is soluble in concentrated acids, it is non-reactive with dilute inorganic and organic acids.

Because of its properties, titanium is useful in a variety of applications. Since it is not easily corroded by sea water, Ti is used to make boat parts. Further, the strength and the light weight allow Ti to use in aircraft, rockets, missiles, etc. Ti is non toxic and bio compatible, making it suitable for biomaterial applications. Ti is a precious metal, hence used to make jewelry too.


Platinum or Pt is the transition metal with the atomic number 78. It is in the periodic table group where Nickel and palladium are in. So has the electric configuration similar to Ni with outer orbitals having s2 d8 arrangement. Pt most commonly forms +2 and +4 oxidation states. It can also form +1 and +3 oxidation states too. Pt is silvery white in color and has a higher density. Atomic mass of Pt is about 195 g mol-1. Pt doesn’t oxidize or reacts with HCl or nitric acid. It is highly resistant to corrosion. Pt also can withstand a very high temperature without melting. (Its melting point is 1768.3 °C). Also, it is paramagnetic. Pt is a very rare metal, which is used in jewelry making. Pt jewelry is also known as white gold jewelry and is very expensive. Further it can be used as the electrode in electrochemical sensors, and cells. Pt is a good catalyst to use in chemical reactions. South Africa is the number one producer of platinum metal.

What is the difference between Titanium and Platinum?

• Pt has 8 d electrons, whereas Ti has only 2 d electrons.

• Pt doesn’t oxidize at any temperature, but Ti oxidizes and forms titanium dioxide.

• Pt is denser than Ti. But Ti is harder than Pt.

• Pt is very rare, making it much more expensive than Ti.

• The color of Ti is much darker than the color of Pt.
