Which of the following possess the highest melting point?

W

The correct answer is option 2. Tungsten (W).

Among the options provided, Tungsten (W) has the highest melting point.

Tungsten, symbolized by the letter W in the periodic table, has the highest melting point of all the elements. Its exceptionally high melting point is primarily due to its strong metallic bonds. Tungsten atoms arrange themselves in a crystal lattice structure, and the bonds between these atoms are very strong, requiring a significant amount of energy to break apart.

When heated, the thermal energy supplied to the tungsten atoms allows them to vibrate more vigorously. However, even at extremely high temperatures, these strong metallic bonds hold the tungsten atoms together until the temperature reaches its melting point. At this point, the thermal energy is sufficient to overcome the forces holding the atoms in place, causing the solid tungsten to transition into a liquid state.

Because of its high melting point and other desirable properties like high tensile strength and resistance to corrosion, tungsten finds applications in various industries, including electronics, aerospace, and manufacturing.
