(a) X, Y and Z are coded letters for three of the metals in the activity series. Some borides of transition elements approach diamond in hardness. A transition element may be defined as a element whose atom or at least one of its simple ions contain partially filled d-orbitals, e.g., iron, copper, chromium, nickel etc.The general characteristic electronic configuration may be written as (n – 1)d1–10ns1–2.The elements of group 12 i.e., Zinc, Cadmium, and Mercury are generally not regarded as transition elements as their atoms and all ions formed have completely filled d-orbitals i.e., these do not have partially filled d-orbitals in atomic state or common oxidation state (Zn2+, Cd2+, Hg2+).Zn (30) = [Ar] 4s2 3d10 Zn2+ = [Ar] 3d104s°Cd (48) = [Kr] 5s2 4d10 Cd2+ = [Kr] 4d105s°Hg (80) = [Xe] 6s2 5d10 Hg2+ = [Xe] 5d106s°. (ii) They are very hard. La3+ and Ce4+ have 4f0 configuration whereas Yb2+ and Lu3+ have 4f14configuration, which makes all these four deficient of unpaired electrons and thus they all are diamagnetic whereas all rest of the lanthanoids have atleast one or more unpaired electron which makes them paramagnetic. These small atoms enter into the void sites between the packed atoms of crystalline transition metals and form chemical bonds with transition metals. It may be noted that atoms of these elements have electronic configuration with 6s2 common but with variable occupancy of 4f level. The lesser number of oxidation states at extreme ends arise from either too few electrons to loose or share (e.g. Whereas there is only one unpaired electron in Cu 2+ and hence CuSO 4.5H 2 O shows lowest degree of paramagnetism. Paiye sabhi sawalon ka Video solution sirf photo khinch kar. If enthalpy of vaporisation is 40.656 kJ the boiling point of water at 23 mm atmospheric pressure will be.

CN-, CO and NO+ are isoelectronic with 14 electrons each and there is no unpaired electrons in the MO configuration of these species. This means that after scandium, d-orbitals become more stable than the s-orbital.Further, +2 state becomes more and more stable in the first half of first row transition elements with increasing atomic number because 3d orbitals acquire only one electron in each of five 3d orbitals (i.e. (v)    The compounds of these metals are usually paramagnetic in nature. paramagnetic: has unpaired e-s that generate a magnetic moment that attracts the cmpd with the unp e-s into a magnetic field; diamagnetic all e- paired: weakly repelled by a magnetic field.

Ch. remains half filled) and electronic repulsion is the least and nuclear charge increases. It is due to its characteristic electronic configuration i. e., (n – 1)d and ns electrons take part in bond formation either by loosing or by sharing of electrons with other combining atoms.The stability of oxidation state depends mainly on electronic configuration and also on the nature of other combining atom.The elements which show largest number of oxidation states occur in or near the middle of series (i.e., 4s23d3 to 4s23d7 configuration). Download the PDF Question Papers Free for off line practice and view the Solutions online. Solution: If (2s-2p) mixing is not operative, then. These fourteen elements are represented by common general symbol ‘Ln’. Our videos prepare you to succeed in your college classes. A group of fourteen elements following lanthanum i.e. To what extent do the electronic configurations decide the stability of oxidation states in the first series of the transition elements? In transition elements, there are greater horizontal similarities in the properties in contrast to the main group elements because of similar ns2 common configuration of the outermost shell.An examination of common oxidation states reveals that excepts scandium, the most common oxidation state of first row transition elements is +2 which arises from the loss of two 4s electrons. Improve concepts using videos, connect with students and teachers globally. (iii)    Decrease in basicity: With the decrease in ionic radii, covalent character of their hydroxides goes on increasing from Ce(OH)3 to Lu(OH)3 and so base strength goes on decreasing. Hence MnSO 4.4H 2 O shows greater paramagnetic nature. So, Na+ is diamagnetic because all its electrons are paired up. (iii) They are chemically inert but retain metallic conductivity. (vi)    Transition metals and their compounds act as good catalysts, i.e., they show catalytic activities. (iv)    Compounds of transition metals are usually coloured. Sc and Ti) or too many d electrons (hence fewer orbitals available in which to share electrons with others) for higher elements at upper end of first transition series (i.e., Cu and Zn). More than one answer may apply. C) The ion has three resonance structures. They are generally non-stoichiometric and neither typically ionic nor covalent.Most of transition metals form interstitial compounds with small non-metal atoms such as hydrogen, boron, carbon and nitrogen.
