The dand fblock elements - Result Question 25
####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:
- (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.
