The Correct Option is C

Approach Solution - 1

The stability of a compound is often related to the charge on the central atom and the nature of its bonding with the ligands. In this case, TII (Tl+1) refers to thallium(I) ions, and TII3 (Tl3+) refers to thallium(III) ions.
Generally, lower oxidation states (e.g., Tl+) are more stable than higher oxidation states (e.g., Tl3+) for heavy elements like thallium. This is due to the presence of additional electron shells that can provide increased shielding and stability for lower oxidation states.
Option (C) TII > TII3 reflects this principle and correctly represents the relationship based on stability.
Therefore, the correct option is (C) : TII > TII3

Approach Solution -2

Due to the inert pair effect, Tl+ is more stable than Tl3+.
Therefore, the correct option is (C) : TII > TII3

P-Block Elements

  • P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
  • P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.

P block elements consist of:
