In moving across the series of metals from scandium to zinc a small change in the values of the first and second ionization energies is observed. Recall that for the transition and inner transition metals, it is necessary to remove the s electrons before the d or f electrons. These inner transition series are covered under rare-earth element and actinoid element. Analogously to the two preceding periods, the next two electrons are added to the next available orbital, namely, the 6 s orbital, producing the next two elements, cesium and barium. In the transition elements, the number of electrons are increasing but in a particular way. Some compounds are diamagnetic.
have large charge/radius ratio.

are hard and have high densities. have high melting and boiling points.
Robert J. They show high melting and boiling points.
Moreover, the additional orbital types each come in larger sets. The general properties of the transition elements are as follows:.

Info Print Print. An example occurs in octahedral, high-spin complexes of manganese II in which all five electrons have parallel spins. In the case of copper, the 3d level is full, but only one electron occupies the 4s orbital.

show variable oxidation states. form coloured ions and compounds.
We daily come across many transition elements. Written By: F. The formation of complexes causes the d orbitals to split into two energy sublevels, which enables many of the complexes to absorb specific frequencies of light.
The 15 elements numbers 58 to 71 of the lanthanide series are rare earth elements. In centrosymmetric complexes, such as octahedral complexes, d-d transitions are forbidden.
