Question: 1 / 400

Which element is known to have the highest melting point?

Iron

Tungsten

The element known to have the highest melting point is tungsten. Tungsten has an exceptionally high melting point of about 3422°C (6192°F), making it ideal for applications requiring materials to withstand extreme temperatures, such as in light bulb filaments and rocket engine nozzles.

Tungsten's strong metallic bonds give it this remarkable property, as it forms a rigid crystal lattice structure that requires a significant amount of energy to break apart, resulting in its high melting point. While other elements like carbon (in the form of diamond) and rhenium also have significant melting points, tungsten surpasses them due to its unique atomic structure and bonding characteristics. Iron, although important in metallurgy and industrial processes, has a much lower melting point compared to tungsten.
