####25. Four successive members of the first row transition elements are listed below with their atomic numbers. Which one of them is expected to have the highest third ionization enthalpy?

[2005]

(a) Vanadium (Z=23)

(b) Chromium(Z=24)

(c) Manganese (Z=25)

(d) Iron (Z=26)

Show Answer

Solution:

  1. (c) For third ionization enthalpy electronic configuration of

Mn has most stable configuration due to half filled d-orbital. Hence, 3rd ionization energy will be highest for Mn.
