d block elements display metallic properties like high tensile strength, malleability, ductility, metallic luster, and high electrical and thermal conductivity. They generally have one or many metallic structures at room temperature. Exceptions for this include zinc, mercury, cadmium, and manganese.
the d block elements exhibit many oxidation states. At the middle of the series, the elements which display the most number of oxidation states can be found. An example of this would be manganese, which can exhibit any oxidation state between +2 and +7.
