Question

The inert pair effect is shown by the electroins in this orbital of TI​

Answer 1

Explanation:

The inert pair effect is defined as the tendency of electrons in the outermost atomic s orbital to remain unionized in compounds of post-transition metals [].

For simplicity, let’s summarize it as the tendency of heavier atoms to form ions with a difference in charge of two. When we say that electrons are inert, we essentially mean that they are spin-paired. An example is helium, with two electrons

Answer 2

Answer:

The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals. The term inert-pair effect is often used in relation to the increasing stability of oxidation states that are two less than the group valency for the heavier elements of groups 13, 14, 15 and 16. The term "inert pair" was first proposed by Nevil Sidgwick in 1927.[1] The name suggests that the outermost s electrons are more tightly bound to the nucleus in these atoms, and therefore more difficult to ionize or share.
