Save for later . the nucler charge increases but the additional 3d electrons reduce its effect, 4s experience relatively small extra attraction from Sc to Zn, second ionisation enegry follows the same pattern, 18 electrons are shielding all the valence electrons, the trend is therefore resembles period 3, it increases across the series as the nuclear charge increasess but shielding effects remains constant, good conductors of electricity as they use both 4s and 3d electrons which are delocalised, However with the exception of copper they are all less good conductors compared to calcium, they do not make coloured compounds or complexes, they do not have variable oxidation states. 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). The general outer electronic configuration of these elements is (n - 1) 10 ns 1-2. Manganese has a very wide range of oxidation states in its compounds. Haloarenes and Method of preparation of Haloarenes, Physical and chemical property of Haloarenes, General method of preparation of Alcohol, Industrial method of preparation of alcohol, Victor Meyers method of distinguish Primary,Secondary and Tertiary alcohol. The two series of inner transition elements that are 4f and 5f series are known as lanthanoids and actinoids respectively. it corresponds to the formal loss of 4s and the unpaired 3d electrons (with the exception of copper), Oxides of elements on low oxidation states turn to be basic and oxides of elements in higher oxidation states turn to be acidic, higher oxidation states tend to involve covalency, Cr, they polarise water mlecules to form axo anions, in the presence of ligands, the d-orbitals are split into different energy levels, the elctrons from lower 3d orbitals absorb energy from light and are excited to a higher energy level, however certain wavelenghts in the visible region are absorbed, the unabsorbed wavelenghts correspond to the colour of solution of the complex absorbed, the difference in energy level of the d-orbitals determine the wavelenghts of light absorbed and hence the colour observed, strength of ligands, oxidation state of metal metal ion and geometry of the complex affect the splitting of d-orbitals and hence the colour of the complex, a complex molecule is a molecule or ion formed by a central metal atom or ion surrounded by one or more ligands e.g [Cu(H, is a species that contains a lone pair of electrons that forms dative bond to a central metal ion or atom eg H, a ligand that donate only one lone pair of electrons eg H, number of lone pairs of eletrons do not determine the number of dative bonds eg H, ligands that can donate two lone pairs of electrons eg H, ligands which form more than one dative bond eg, i) neutral ligands without an overall charge, 2-coordinate complexes are generally linear.eg diamine silver(I) complex, 4-coordinate complexes are generally tetrahedral but can also be square planar e.g [CuCl, 6-coordinate complexes made from monodentate ligands are all octahedral e.g [Cu(H. Ligand exchange is the replacement of one ligand by another in a complex. Transition Elements. Transition Elements 2.
