Question

The element that has the highest melting point in the 3d series is:

• A. V
• B. Cr
• C. Mn
• D. W

Hint:

When studying the melting points of transition metals, look for trends where the melting points tend to increase and peak at the middle of the series, particularly in the 3d series with tungsten having the highest.

Answer 1

The Correct Option is D

The melting point of elements generally increases across the transition series up to the mid-3d block, and then starts to decrease. Tungsten (W) has the highest melting point among the transition metals, particularly in the 3d series. - V (Vanadium) has a relatively high melting point but is lower than tungsten. - Cr (Chromium) also has a high melting point, but tungsten's is higher. - Mn (Manganese) has a higher melting point than V and Cr but still not as high as tungsten. Thus, W (Tungsten) has the highest melting point in the 3d series.
