Question:
Why do transition metals have high enthalpy of atomization? Which element of the 3d-series has the lowest enthalpy of atomization?
Why do transition metals have high enthalpy of atomization? Which element of the 3d-series has the lowest enthalpy of atomization?
Show Hint
Zinc (Zn) has a fully filled \( 3d^{10} \) configuration, so it has fewer unpaired electrons and weaker bonding, leading to the lowest enthalpy of atomization in the 3d series.

Solution and Explanation
- Transition metals have a high enthalpy of atomization due to the large number of unpaired d-electrons in their atoms, resulting in strong metal-metal bonding and interatomic interactions.
- The enthalpy of atomization increases as the metal atoms form stronger bonds due to these unpaired d-electrons.
- The element Zinc (Zn) from the 3d-series has the lowest enthalpy of atomization, because it has a filled d-orbital (\(3d^{10}\)), resulting in weaker metal-metal bonding.

- Transition metals have incomplete d-subshells either in the neutral atom or in their ions. The presence of partly filled d-orbitals in their atoms makes transition elements different from non-transition elements. With partly filled d-orbitals, these elements exhibit certain characteristic properties such as:
- Display of a variety of oxidation states
- Formation of coloured ions
- Entering into complex formation with a variety of ligands
The transition metals and their compounds also exhibit catalytic properties and paramagnetic behaviour. The transition metals are very hard and have low volatility. An examination of the E0 M2+/M values shows the varying trends:

Questions Asked in CBSE CLASS XII exam
- The nature of bonding, structure of the coordination compound can be explained to some extent by valence bond theory. The central metal atom/ion makes available a num ber of vacant orbitals equal to its coordination number. The appropriate atomic orbitals (s, p and d) of the metal hybridize to give a set of equivalent orbitals of definite geome try such as square planar, tetrahedral, octahedral and so on. A strong covalent bond is formed only when the orbitals overlap to the maximum extent. The d-orbitals involved in the hybridization may be either inner d-orbitals i.e. (n–1) d or outer d-orbitals i.e. nd. The complexes formed are called inner orbital complex (low spin complex) and outer orbital complex (high spin complex) respectively. Further, the complexes can be para magnetic or diamagnetic in nature. The drawbacks of this theory are that this involves number of assumptions and also does not explain the colour of the complex.

- In a galvanic cell, chemical energy of a redox reaction is converted into electrical energy, whereas in an electrolytic cell the redox reaction occurs on passing electricity. The simplest galvanic cell is in which Zn rod is placed in a solution of ZnSO4 and Cu rod is placed in a solution of CuSO4. The two rods are connected by a metallic wire through a voltmeter. The two solutions are joined by a salt bridge. The difference between the two electrode potentials of the two electrodes is known as electromotive force. In the process of electrolysis, the decomposition of a substance takes place by passing an electric current. One mole of electric charge when passed through a cell will discharge half a mole of a divalent metal ion such as Cu2+. This was first formulated by Faraday in the form of laws of electrolysis.
