WebThe most reactive metal is placed at the top of the series, and the least reactive metal is placed at the bottom of the series.The reactivity series of metals is as follows:Potassium (K) > Sodium (Na) > Calcium (Ca) > Magnesium (Mg) > Aluminium (Al) > Zinc (Zn) > Iron (Fe) > Tin (Sn) > Lead (Pb) > Hydrogen (H) > Copper (Cu) > Silver (Ag) > Gold ... Web1. Barrier methods e.g. grease, paint, oil or plastic. ~ surface of metal is coated to protect from conditions. 2. Galvanisation when zinc coats iron to protect. 3. Sacrificial protection. ~ more reactive metal covers surface of less reactive metal => more reactive metal corrodes instead, leaving less reactive metal preserved.
