What is the reason behind the trend of increasing values of second ionization enthalpy as the effective nuclear charge increases?
Options
- ADecrease in the number of d electrons
- BIncrease in the number of s electrons
- CLoss of exchange energy
- DIncrease in the number of p electrons
Correct answer
C. Loss of exchange energy
Step-by-step solution
The trend of increasing values of second ionization enthalpy as the effective nuclear charge increases is due to the loss of exchange energy.
