The second transition series metals are shown below. 
-Which has the highest melting point?
A)Y 
B)Mo 
C)Tc 
D)Cd

Quizplus · Accepted Answer

The melting points of transition metals increase up to the middle of the series and then decrease. Mo is the last element in the second transition series and therefore has the highest melting point compared to the other options. Choices A) Y and C) Tc are not in the second transition series, and choice D) Cd is not a transition metal.
