(ii) Which element of the first transition series has highest third ionisation enthalpy? Cu is the only metal in the first transition series (3d series) which shows +1 oxidation state most frequently. The d-block elements are divided into the first transition series (the elements Sc through Cu), the second transition series (the elements Y through Ag), and the third transition series (the element La and the elements Hf through Au). Actinium, Ac, is the first member of the fourth transition series, which also includes Rf through Rg. The closest relationships are usually to be found among the three elements in each vertical group in the periodic table, although within each group the element of the first series usually differs more from the other two than they differ from each other. For the elements of first transition series (except scandium) + 2 oxidation state is the most common oxidation state. In first transition series, electrons are filled only in d orbitals but in second and third transition series, electrons are filled in d- and f-orbitals. Elements of the Second Transition series or 4d-Transition series: This series consists of the elements from yttrium (Y, Z = 39) to cadmium (Cd, Z = 48). A few of the chemical trends to be found in the first transition series may be capsulized. The most common examples of the transition elements are copper, iron, and silver. The second transition series : Yttrium (Y, Z =39) to Cadmium (Cd, Z = 48) : addition of electrons in 4d orbitals. The screening effect of f-orbital is lower than that of d-orbital. More to known as oxidation states of the first d-block series ⦠A few of the chemical trends to be found in the first transition series may be capsulized. The position of first transition series lies amid the fourth, fifth, sixth, and seventh groups. Elements (metals) of the first transition series; 2. The chemistry of the lightest element (V) is dominated by lower oxidation states, especially +4. The reactivity and structural properties of first row transition metals and their compounds depend on the electronic configuration of the d electrons of the metal. The lesser number of oxidation states at extreme ends arise from either too few electrons to loose or share (e.g. There are four series of transition elements : i) ii) iii) iv) The first transition series : Scandium (Sc, Z = 21) to Zinc (Zn, Z=30) : addition of electrons in 3d orbitals. As we move from left to right in a transition metal series, the ionization enthalpy increases as expected. Oxidation numbers (states) of transition metals; 6. The significance of the 4s subshell; 5. Solution : Due to configuration, metalic bonds are weak. ii) The second transition series : Yttrium (Y, Z =39) to Cadmium (Cd, Z = 48) : addition of electrons in 4d orbitals. Elements of the first transition series are good catalysts, finely divided nickel is used as a catalyst for hydrogenation of oil due to the presence of the 4S and 3d electrons which form bonds between the reacting molecules and the surface of the catalyst which leads to: Increasing the concentration of the reactants at the surface of the catalyst. 5. Hence the d-electrons effect the properties of the elements to a great extent.Thus ,ions with similar d n configuration (n = 1 â 9 have similar magnetic and electronic properties.
