Transition elements are those in which d or f-subshells are partially filled in the atomic state or in atomic state. They include the elements of Groups IIB and IIIB as non-typical and IB, IVB to VIIIB groups elements as typical transition elements. They have unique properties and characteristics. They contain complex compounds. Iron is an important Transition element. Steel can be manufactured by Open Hearth and Bessemer&#8217;s process. Corrosion is a process which occurs in metals. There are different methods to prevent metal from corrosion. Chromates and Dichromate are important salts of Chromic and Dichromic acids<span style=\"font-weight: bold;\">.\u00a0<\/span>So, this is the introduction of this chapter.
