State all the exceptions to the general trend of metallic and non metallic character with reasons.

Dear Student,
The general trend in metallic character is that the metallic character decreases across the period while non-metallic character increases .The trend down a group is that the metallic character increases  down the group while non-metallic character decreases . All the elements follow the common properties of metals except a few of transition metals such as Zn , Cd, Mn , Hg these metals do not exhibit properties of malleability , ductility , thermal and electrical conductivity
