The following pictures show the electron populations of the composite s-d bands for four different transition metals. 
-Which metal has the highest melting point?
A)metal (1) 
B)metal (2) 
C)metal (3) 
D)metal (4)

Quizplus · Accepted Answer

The metal with the highest melting point is typically one that has a high number of valence electrons, as these electrons are responsible for the metallic bonding that holds the metal atoms together. In the given pictures, metal (3) has the highest electron population in the s and d bands, indicating a higher number of valence electrons and therefore a higher melting point compared to the other metals.
