![]() ![]() Metals in this series comprise titanium (Ti), vanadium (v), chromium (Cr), Manganese (Mn), Iron (Fe), cobalt (Co), nickel (Ni) and copper (Cu). The first transition series metals from scandium (Sc) to zinc (Zn) in period 4 are of main focus and they are principally significant in industry.

All the transition elements are metals of great economic significance. ![]() ![]() They occupy three rows or periods (Periods 4, 5 and 6 of the periodic table) having ten elements in each and every row. The word transition element is only used for an element that consists of partially or incompletely filled d-orbitals. In the d-block the penultimate shell, that is, the orbital subsequent to the outermost orbital, of electrons is being expanded from eight to eighteen via the addition of d-electrons. Transition or d-block elements are so called as their position in the periodic table is between the s and p block elements, and their properties are transitional among the highly reactive metallic elements of the s-block that usually form ionic compounds, and the elements of the p-block that are largely non-metallic forming covalent compounds. We are familiar that the periodic table positioned some elements between the group II and group III are known as transition elements. Metals-Transition metals, Chemistry tutorial ![]()
