Think of Tungsten's atoms as being held together by ultra-strong magnetic glue, requiring an immense amount of thermal energy to break their grip compared to metals like Gold or Iron.

Tungsten is 'Tough as Titan'—the T-T association helps remember it handles the 'Top Temperature'.

The extremely high melting point of Tungsten is due to the strength of the metallic bonds between its atoms. Tungsten has a half-filled 5d electron shell, which allows for strong covalent character in its bonding, significantly increasing the energy required to disrupt the crystal lattice structure. The large number of delocalized electrons per atom contributes to a very high bond dissociation energy.

Always remember that while Tungsten is the metal with the highest melting point, Carbon is the element that remains solid at the highest temperature (sublimation), which is a common trick in competitive exams.
