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.

Read the passage given below and answer the following questions:The d block elements are the 40 elements contained in the four rows of ten columns (3-12) in the periodic table. As all the d block elements are metallic, the term d-block metals is synonymous. This set of d-block elements is also often identified as the transition metals, but sometimes the group 12 elements (zinc, cadmium, mercury) are excluded from the transition metals as the transition elements are defined as those with partly filled d or f shells in their compounds. Inclusion of the elements zinc, cadmium and mercury is necessary as some properties of the group 12 elements are appropriate logically to include with a discussion of transition metal chemistry. The term transition element or transition metal appeared to derive from early studies of periodicity such as the Mendeleev periodic table of the elements. His horizontal table of the elements was an attempt to group the elements together so that the chemistry of elements might be explained and predicted. In this table there are eight groups labeled I-VIII with each subdivided into A and B subgroups. Mendeleev recognized that certain properties of elements in Group VIII are related to those of some of the elements in Group VII and those at the start of the next row Group I. In that sense, these elements might be described as possessing properties transitional from one row of the table to the next.In the following questions, a statement of assertion followed by a statement of reason is given.
