Dilute acids have no action on mercury except dil.. - On Shaking vigorously alone or with fats or sugar it changes to grey powder. - Nowadays electrolytic oxidation is prefered. Important notes are also helpful for revision when you have less time and have to study many topics. These are interconvertible. It is very inert and not attacked by oxygen, water and acids. The elements belonging to this series are also known as. On this basis, they are differentiated in lanthanides and actinides. The elements in which the filling of atomic orbitals by electrons take place in f subshells, two levels inside the outer subshell, are known as inner transition elements.
