The magnetic behaviour of actinoids is more complex and cannot be explained, where for lanthanoids it can be explained and calculated by spin only formula.
Though the magnetic behaviour variation is similar to that of lanthanoids but still lanthanoids have greater magnetic moments.
Account for the following facts:
The reduction of a metal oxide is easier if the metal formed is in liquid state at the temperature of reduction.
Account for the following facts:
The reduction of Cr2O3 with Al is the thermo-dynamically feasible, yet it does not occur at room temperature.
