Similarities and Differences between Transition Metals and Representative Metals

  • Transition metals have stronger interparticle forces and hence are harder than representative metals. They have higher densities and higher melting points.
  •  Transition metals exhibit variable oxidation states whereas representative metals rarely show variable oxidation states
  •  Transition metals form a large number of coordination complexes. Most of these complexes are coloured and paramagnetic. Representative metals have less tendency to form complexes. These complexes are generally white.
  • Transition metals are less reactive than representative metals. This is due to their less electropositive nature.
  •  A comparison of some chemical properties of transition metals and some representative metals has been given in Table 19.8.
