Short Answer TypeThe melting points depend upon the inter atomic bonding, more the number of electrons given by a metal higher in its interatomic bonding (metallic bonding) and thus higher will be its melting point.
In d-block elements due to the involvement of both ns and (n – 1)d electrons, the number of electrons involved are higher and therefore stronger interatomic bonding and higher melting point.
Long Answer TypeWhat are interstitial compounds? Why are such compounds well known for transition metals?
Describe the preparation of potassium dichromate from iron chromite ore. What is the effect of increasing pH on a solution of potassium dichromate?
Short Answer TypeDescribe the oxidising action of potassium dichromate and write the ionic equations for its reaction with:
(a) iodide (b) iron (II) solution and (c) H2S.
