- Solubility is ability of a substance, the solute, to form a solution with another substance, the solvent.
- Insolubility is the opposite property, the inability of the solute to form such a solution.
a) Transitional elements have a metallic character because they have low ionization energies as well as several empty orbitals in their outer shells.
b) Due to the presence of unpaired electrons in the d-orbitals, most of the transition metals ions and their compounds are paramagnetic.
c) They show catalytic properties because of the presence of vacant d-orbitals, ability to exhibit variable valencies and they have a tendency to form complex compounds.
