Question

The transition metal having highest … ionisation enthalpy is :

Accepted Answer

Option A. The third ionization enthalpy refers to the energy required to remove the third electron from a di-positive ion (…) to form a tri-positive ion (…). In the case of transition metals, the energies involved in removing the third electron are typically higher than for the first and second electrons due to an increasing effective nuclear charge and the electrons being removed from closer energy levels to the nucleus or from a half-filled or full-filled d-subshell which is relatively more stable.
