The Question : On the basis of the figure given below, answer the following questions:a. Why does Manganese has lower melting point than Chromium?b. Why do transition metals of 3d series have lower melting points as compared to 4d series?c. In the third transition series, identify and name the metal with the highest melting point.
Solution for the question :
(a) Manganese is having lower melting point as compared to chromium, as it has the highest number of unpaired electrons, strong interatomic metal bonding, hence no delocalisation of electrons.
(b) There is much more frequent metal-metal bonding in compounds of the heavy transition metals i.e 4d and 5d series, which accounts for lower melting point of 3d series.
(c) Tungsten
