(i) Transition metals exhibit enthalpy of atomisation.
(ii) Transition metals form interstitial compounds.
Explain why:
(i) Transition elements are metals?
(ii) Lanthanides are uniformly trivalent?
Write the preparation of :
(i) Potassium dichromate from chromite.
(ii) KMnO4 from pyrolusite.
Long Answer TypeShort Answer TypeHow do you explain the paramagnetism and colour exhibited by compounds of transition metals?
Vanadium ion has a magnetic moment of 1.73 BM. What is the symbol of the ion? (Atomic number of V = 23)
Why are the compounds of transition elements usually coloured, both in the solid state and in aqueous solution?
The compounds of transition element are usually coloured both in solid state and in aqueous solution. The colour of these complex is due to adsorption of some radiation form visible light which is used in promoting an electron form one of the d- shells to another.
