NEETChemistryClassification of Elements and Periodicity in Properties
How do ionization enthalpies of transition elements (3d series) compare to those of group 1 and 2 metals?
Options
- AThey are higher.
- BThey are lower.
- CThey are the same.
- DThey are negligible.
Correct answer
A. They are higher.
Step-by-step solution
Transition elements (3d series) are less electropositive than group 1 and 2 metals, indicating that their ionization enthalpies are higher.
