1.	Name one element in which corrosion is not proved to be wasteful and how it’s used ?(2 marks)
Answer» In Aluminium, Beryllium, Chromium etc.... corrosion results in a thin oxide layer FORMATION. This renders it a inert layer on SURFACE which prevents further corrosion. THUS, in those elements corrosion is proved to be useful. In case of aluminium, the layer formed is Al₂O₃(Aluminium oxide) layer.
