Question

Which oxidation state is observed to be more stable in group 14 elements with the increase in
atomic number?​

Answer 1

Answer:

+2

The +1 oxidation state in group 13 and +2 oxidation state in group 14 becomes more and more stable with increasing atomic number.

Answer 2

+2 oxidation state is observed to be more stable in group 14 elements with the increase in  atomic number.

• As one moves down the group, new shells get added to accommodate the electrons.
• In Group - 14, higher elements (i.e. elements with greater atomic number) have d and f shells which leads to the inert pair effect.
• In other words, there is an inability of ns² electrons to participate in the bonding as they are shielded.
• Thus, the tendency of +2 oxidation state increases down the group.
