Which of the following metal is having the highest melting point?

Tungsten

The correct answer is: (1) Tungsten

Tungsten (symbol: W) has the highest melting point among the metals listed. It has a melting point of approximately \(3422^oC\) \((6192 ^oF)\), which is higher than that of platinum, palladium, and gold. Tungsten's high melting point is a result of its strong metallic bonding and the stability of its crystal structure at high temperatures. Due to its exceptional high-temperature properties, tungsten is commonly used in applications where high melting points are required, such as in the production of lightbulb filaments, electrical contacts, and various high-temperature tools and equipment.
