Question

Why oxidation state +1 become more predominant in moving from boron to thalium in boron family?

Answer 1

Here is your answer ⤵⤵⤵

This is because of the inert pair effect. Thus, although Ge, Sn, and Pb show both the +2 and + 4 states, the stability of the lower oxidation state increases and that of the higher oxidation state decreases on moving down the group. 2. Boron and thallium belong to group 13 of the periodic table.
