Current Question (ID: 18837)

Question:

$\text{The ionization potential values of d-block elements as compared to the ionization potential values of f-block elements are:}$

Options:

1. $\text{Higher}$
2. $\text{Equal}$
3. $\text{Lower}$
4. $\text{Can't compare.}$

Solution:

$\text{Ionisation potential of d-block element is higher than f-block elements.}$ $\text{STEP 1:}$ $\text{The ionization energy increases due to the increase in the nuclear charge with atomic number at the beginning of the series. Gradually, the shielding effect of the added electrons also increases.}$ $\text{This shielding effect tends to decrease the attraction due to the nuclear charge. These two opposing factors lead to a rather gradual increase in the ionization energies in any transition series.}$ $\text{STEP 2:}$ $\text{Ionisation potential values of d-block elements as compared to ionization potential value of f-block elements are higher because removal of electron is easier in f-block elements due to more shielding.}$
