Respuesta :

Among the elements in the periodic table, tungsten metal is expected to have the highest melting point.

Tungsten, having atomic number 74 belongs to the 6th group and 6th period of the periodic table.

It is the metal with the highest melting point i.e 3422°C . For this reason, tungsten is used as a metallic component in the filaments of electric bulbs and in cathode ray tubes.

Tungsten is considered a refractory metal due to its heat-hesistance nature. on the other hand, alkali metals such as Li,Na,K  have low melting points because of their large size of atoms and due to which the binding energies of the atoms in the crystal lattice is comparatively low, resulting in low melting point.
