The ionisation energies of transition elements are-a)Less than p-block...
Explanation:

The ionization energy is the amount of energy required to remove an electron from an atom or ion in the gaseous state. It is measured in kilojoules per mole (kJ/mol). The ionization energy of an element depends on its atomic structure and the number of electrons in its outermost energy level.

Transition Elements:

Transition elements are the elements in the d-block of the periodic table. They have partially filled d orbitals and their outermost energy level is the (n-1)d subshell. The ionization energies of transition elements are generally lower than those of p-block elements. This is because the d orbitals are closer to the nucleus compared to the p orbitals, resulting in a stronger attraction between the nucleus and the outermost electrons. Therefore, it requires less energy to remove an electron from a transition element compared to a p-block element.

P-Block Elements:

P-block elements are the elements in the p-block of the periodic table. They have partially filled p orbitals and their outermost energy level is the np subshell. The ionization energies of p-block elements are generally higher than those of transition elements. This is because the p orbitals are farther from the nucleus compared to the d orbitals, resulting in a weaker attraction between the nucleus and the outermost electrons. Therefore, it requires more energy to remove an electron from a p-block element compared to a transition element.

S-Block Elements:

S-block elements are the elements in the s-block of the periodic table. They have partially filled s orbitals and their outermost energy level is the ns subshell. The ionization energies of transition elements are generally higher than those of s-block elements. This is because the s orbitals are closer to the nucleus compared to the d orbitals, resulting in a stronger attraction between the nucleus and the outermost electrons. Therefore, it requires less energy to remove an electron from an s-block element compared to a transition element.

Summary:

In summary, the ionization energies of transition elements are generally less than p-block elements and more than s-block elements. This is due to the differences in the distances between the orbitals and the nucleus, resulting in varying strengths of attraction between the nucleus and the outermost electrons.

Similar Class 12 Doubts

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.
