Titanium vs Tungsten
Both, titanium and tungsten are d block elements. They are commonly known as transition metals. Both metals are used for jewelry making because of their color, hardness and durability.
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 electronic 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 high 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. Through Ti is soluble in concentrated acids, it is non-reactive with dilute inorganic and organic acids.
Properties of titanium make that useful in a variety of applications. Since it is not easily corroded by seawater, Ti is used to make boat parts. Further, the strength and the lightweight 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.
Tungsten, which is shown by the symbol W, is a transition metal element with the atomic number 74. It is a silvery white color element. It belongs to the group six and period 6 in the periodic table. The molecular weight of tungsten is 183.84 g/ mol. The electronic configuration of tungsten is [Xe] 4f14 5d4 6s2. Tungsten shows oxidation states from −2 to +6, but the most common oxidation state is +6. Tungsten is resistance to the reactions of oxygen, acids and alkalis when it is in bulk amounts. Scheelite and wolframite are the most important types of tungsten minerals. Tungsten mines are located mainly in China. Other than this mine, there are some in countries like Russia, Austria, Bolivia, Peru and Portugal. Tungsten is more popular for their usage as bulb filaments. Very high melting point (3410 °C) of tungsten has allowed its usage in bulbs. In fact, it has the highest melting point of all the elements. Its boiling point is also very high compared to most other elements. It is about 5660 °C. Tungsten is also used in electric contacts and arc-welding electrodes.
What is the difference between Titanium and Tungsten?
• Atomic number of Ti is 22, and the atomic number of tungsten is 74.
• Tungsten has more d electrons than titanium. In titanium, there are only 2 d electrons and tungsten has 24.
• Tungsten is much heavier than Ti.
• Ti is in group 4 in the periodic table, and W is in group 6.
• Ti mostly forms compounds with +4 oxidation state whereas tungsten moistly forms compounds with +6 oxidation state.
• Tungsten has a higher melting point and boiling point compared to Ti.
