• Atomic Structure: Titanium has a relatively simple atomic structure. In the center of its core (nucleus), there are 22 protons and the same number of electrons to maintain its neutrality. Its electronic configuration is 1s² 2s² 2p? 3s² 3p? 4s² 3d², which shows that it has 22 electrons divided into various electron shells. This is an example of the atomic structure of a metal element in the periodic table.

Rhodium:

• Appearance Characteristics: Rhodium has a very different from titanium. It is a heavy metal with a very shiny silvery white color. Rhodium is one of the shiniest elements among the noble metal elements.
• Atomic Structure: Rhodium has a more complex atomic structure than titanium because it is a heavier element. At the center of its core, rhodium has 45 protons and 45 electrons to maintain its neutrality. Its electron configuration is 1s² 2s² 2p? 3s² 3p? 4s² 3d¹? 4p? 5s² 4d?, which shows that it has 45 electrons divided into various electron shells. Rhodium is part of the group of transition metal elements in the periodic table, which tend to have more complicated electronic configurations compared to non-metal elements.

Hardness:

• Titanium: Titanium has a relatively high hardness, although not as hard as some other metals such as stainless steel . The hardness of titanium depends on the type of alloy, but in most cases, it is hard enough to be used in engineering applications that require strength and wear resistance.
• Rhodium: Rhodium has much greater hardness higher than titanium. Rhodium is one of the hardest metals there is. Its hardness makes it particularly suitable for use as a protective coating on jewelry, as it provides a surface that is resistant to scratches and abrasion.

Corrosion Resistance:

• Titanium: One of the main advantages of titanium is its resistance to corrosion. Titanium has the natural ability to form an oxide layer that is resistant to corrosion when exposed to air or water. Therefore, titanium is often used in applications that require corrosion resistance, such as in the aircraft industry, chemical equipment, and medical implants.
• Rhodium: Rhodium also has strong corrosion resistance Very good. Rhodium does not react easily with many chemicals or corrosive environments. This is one reason why rhodium is used so widely in precious metal jewelry, where corrosion resistance is critical to maintaining its luster and beauty.

Overall, both titanium and rhodium have similar mechanical properties. special, but they are used in different applications due to differences in hardness and corrosion resistance uses. Titanium is generally used in engineering applications, while rhodium is used in the jewelry industry and chemical catalysis.

Natural Availability

The natural availability of titanium and rhodium on Earth is very different due to their chemical properties and geological presence both of them. The following is an explanation of the source and natural distribution of these two elements:

Titanium:

• Source: Titanium is an element which is relatively abundant in the earth’s crust. It is a hidden element in the 9th position in terms of abundance in the earth’s crust. The main sources of titanium are minerals such as ilmenite, rutile, and anatase. Ilmenite is the most common mineral and contains approximately 45-60% titanium dioxide (TiO2).
• Distribution: Ilmenite and other mineral sources containing titanium can be found in various locations throughout the world, including Australia, Canada, Norway, China and the United States. Most titanium production comes from ilmenite mining and processing of the mineral.

Rhodium:

• Source: Rhodium is a much rarer element than titanium. It belongs to the group of precious metals, known for its very low abundance in nature. Most of the rhodium used comes from nickel-platin mining, because rhodium is often found as one of the accompanying metals.
• Distribution: Rhodium has a very limited natural distribution. The primary source of rhodium is nickel-platin deposits located in several locations around the world, including South Africa, Russia, Canada, and Zimbabwe. South Africa is known as a major producer of rhodium as it has the world’s largest reserves.

In terms of natural availability, titanium is much more common than rhodium. Titanium can be found in quite large quantities in many regions, while rhodium is one of the rarest and most difficult to find precious metals. Therefore, this difference in natural availability also affects the relative prices of the two elements, with rhodium being much more expensive than titanium.
