The transition metals are a group of metals that are found in the middle of the periodic table. The alkaline earth metals, beginning with beryllium are to the left and the boron group elements are to the right are termed as "transition element". There are more transition metals than any other groups in the periodic table. Transition metals have several general properties. They are harder and less reactive than the alkaline earth metals. They are also harder than the post transition metals. They make colorful chemical compounds with other elements. Most of them have more than one oxidation state. Like other metals, they are electrical conductors. Some of the transition metals are necessary for human health, such as iron, zinc, and chromium. | Dynamics of transition metal and their application in biomedical industry
