The solutions which boil at a constant temperature like a pure liquid and possess the same composition in liquid, as well as vapour state are called azeotropes. The components of azeotropes cannot be separated by fractional distillation. Only non-ideal solutions form azeotropes. Solutions with negative deviation form maximum boiling azeotrope and the solutions with positive deviation form minimum boiling azeotrope. The boiling point of azeotrope is never equal to the boiling points of any of the components of the azeotrope.

The actinoids include the fourteen elements from $Th$ to $Lr.$ The actinoids are radioactive elements and the earlier members have relatively long half$-$lives, the latter ones have half$-$life values ranging from a day to $3$ minutes for lawrencium. The latter members could be prepared only in nanogram quantities. Actinoids show a greater range of oxidation states. The elements, in the first half of the series frequently exhibit higher oxidation states. The actinoids resemble the lanthanoids in having more compounds in $+3$ state than in the $+4$ state. All the actinoids are believed to have the electronic configuration of $7s^2$ and variable occupancy of the $5f$ and $6d$ subshells. The magnetic properties of the actinoids are more complex than those of the lanthanoids. The variation in the magnetic susceptibility of the actinoids with the number of unpaired $5f$ electrons is roughly parallel to the corresponding results for the lanthanoid.
