Answer 2

$\huge\underline\mathbb\color{gray}{ANSWER}$

• As we move down a group, atomic radius increases due to the addition of a new energy level.
• Even metallic properties increases while moving down the group as decrease in attraction between the nuclei and the outermost electrons causes the outermost electrons to be loosely bound and thus able to conduct heat and electricity.
