Which is more stable among Tl^(+3) and Tl^(+1). Why? |
|
Answer» Solution :`Tl^(1+)` is more stable than `Tl^(3+)` . It is DUE to inert pair effect. With increases in SIZE of atom in a GROUP. The s electrons present in the outermost orbit are reluctant in involving bond FORMATION. Hence, in thallium, only p ELECTRON involves in bond formation. |
