Question

Which of the following statement is correct with respect to the property of elements with an increase in atomic number in the carbon family (group 14)

• A. Atomic size decrease
• B. Ionization energy increase
• C. Metallic character decrease
• D. Stability of +2 oxidation state increase

Answer 1

The correct option is D

Stability of +2 oxidation state increase

As we go down the group inertness of $n{s}^2$ pair increase hence tendency to exhibit +2 oxidation state increases and that of +4 oxidation state decreases.
