The first ionization energy of the d-block elements are?a)Lesser than ...
The first ionization energy of the d-block elements are between s and p-block elements. Thus they are more electropositive than p-block elements and less electropositive than s-block elements.

The first ionization energy of the d-block elements are?a)Lesser than ...
Explanation:
The first ionization energy refers to the amount of energy required to remove the outermost electron from a neutral atom. The d-block elements are the transition metals which have partially filled d-orbitals.
Comparison with p-block elements:
- The p-block elements have a completely filled outermost s-orbital and partially filled p-orbitals.
- The first ionization energy of the d-block elements is generally between that of the s and p-block elements.
- This is because the partially filled d-orbitals shield the outermost electrons from the positively charged nucleus to some extent, making it easier to remove the outermost electron compared to the p-block elements.
Comparison with s-block elements:
- The s-block elements have a completely filled outermost s-orbital and no d-orbitals.
- The first ionization energy of the d-block elements is generally less than that of the s-block elements.
- This is because the d-electrons are further from the nucleus and provide additional shielding, making it easier to remove the outermost electron compared to the s-block elements.
Therefore, the correct answer is option B: between s and p-block elements.
