Sometimes the elements of column twelve of the periodic table (zinc, cadmium, mercury, copernicium) are not included as part of the transition metal group. Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration. These elements, all of which are metals, include some of the best-known names on the periodic table — iron, gold, silver, copper, mercury, zinc, nickel, chromium, and platinum among them. According to the new table, the row… These are subcategorized by two individual series called the Lanthanoids and Actinoids and they occupy the … The term "transition element" was invented for them in 1921. These metals are harder and less reactive than. The ions of transition metals absorb the radiation of a particular wavelength and the rest is reflected, imparting colour to the solution. They form coloured compounds. The symbol of the chemical element silicon is “Si” with atomic number 14. Students would then learn about transition metals in detail in inorganic chemistry, in the second term. The transition metals consist of 38 elements in the periodic table situated in the groups 3-12. Post transition metals have very poor mechanical properties. OTHER METALS. The term "transition element" was invented for them in 1921. They are known as inner transition metals. Transition metals acts as catalyst due to the following reasons:(i) Their partially empty d-orbitals provide surface area for reactant molecules. The alkaline earth metals, beginning with beryllium are to the left and the boron group elements are to the right.
