Transition metals show paramagnetism
Due to characteristic configuration
High lattice energy
Due to variable oxidation states
Due to unpaired electrons
Correct order of atomic Radii (Metallic radii)
When an acidified solution of ferrous ammonium sulphate it treated with potassium permanganate solution, the ion which is oxidised is
The stability of $Cu ^{2+}$ is more than $Cu ^{+}$salts in aqueous solution due to -
Although $\mathrm{Cr}^{3+}$ and $\mathrm{Co}^{2+}$ ions have same number of unpaired electrons but the magnetic moment of $\mathrm{Cr}^{3+}$ is $3.87$ $B.M.$ and that of $\mathrm{Co}^{2+}$ is $4.87$ $B.M.$ Why ?
Write a note on oxides and oxoanions of transition elements.
