NCERT Solutions for Class 12 Chemistry Chapter 8: Points to Remember

Below-mentioned are some of the important points to remember from NCERT Class 12 Chemistry Chapter 8 to ace your exams:

  • All transition elements are metals. They possess characteristic properties of metals such as high tensile strength, malleability, ductility, and thermal and electrical conductivity.
  • Transition elements have high melting and boiling points due to stronger interatomic bonding.
  • The atomic and ionic radii of transition elements are smaller than those of s-block elements but larger than those of p-block elements.
  • Transition elements exhibit higher enthalpies of atomisation due to stronger interatomic bonding.
  • Among the elements of the first transition series, zinc has the least enthalpy of atomisation.
  • Among the elements of the 3d-3d-transition series scandium does not show variable oxidation states while manganese shows maximum number of oxidation states.
  • Transition elements form coloured complexes. Colour of the complexes is due to absorption of light energy due to d-d transitions in partially filled d-orbitals.
  • The first series transition metal oxides are generally formed by the reaction of metals with oxygen at high temperatures. These oxides may be acidic, basic or amphoteric. These oxides dissolve in acids and bases to form oxometallic salts. K2CrO4, K2Cr2O7 and KMnO4 are common examples of oxometallic salts.
  • Lanthanoids are a series of elements which involve filling of 4f- subshell. These are fourteen elements following lanthanum from Cerium to Lutetium.
  • Actinoids are a series of elements which involve filling of 5f- subshell. These are fourteen elements following Actinium from Thorium to Lawrencium.
  • The common oxidation state of lanthanoids and actinoids is +3.
