Which one of the following metals is expected to have the highest melting point?
A)La
B)Nb
C)Hg
D)Pd

Question

Quizplus · Accepted Answer

Out of the given options, niobium (Nb) is expected to have the highest melting point because it has the highest atomic number, which indicates a higher number of protons and electrons than the other metals. This leads to stronger metallic bonding between the niobium atoms, resulting in a higher melting point. La, Hg, and Pd have lower atomic numbers and, therefore, weaker metallic bonds, resulting in lower melting points.
