Web28 Sep 2024 · This is a destructive test in that the metal surface is vaporized to a depth of 50 angstroms (50Å) or 0.1nm across an area of 200Å (20nm). It is important to remember that the goal of the passivation process is to remove iron, iron oxides and other residual metals from the upper 20-50Å of the stainless steel surface. WebVerified by Toppr Explanation: Inert pair effect can be defined as the reluctance of the outermost shell s− electrons to participate in bonding. It is most commonly observed for group 4 and group 5 elements. The lower oxidation states of the elements of this group are formed due to the inert pair effect.
