Worked Solution & Example Answer:The elements in Group IV of the periodic table become more metallic in character down the group - VCE - SSCE Chemistry - Question 12 - 2004 - Paper 1
Step 1
B. atomic size increasing.
Answer
The trend of increasing metallic character down Group IV of the periodic table can be attributed to the increasing atomic size. As we move down the group, additional electron shells are added, resulting in an increase in atomic radius. This increase in size leads to a decrease in ionization energy, making it easier for the atoms to lose electrons and exhibit metallic behavior.
Consequently, the larger atomic size plays a significant role in enhancing the metallic characteristics of elements in this group.
