The D And F Block Elements Ques 18
18. 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.
