HEY MATE.....
As u know the atomic size increases as we go down the group because zeff decreases.... that is nucleus attraction towards the electrons decreases.....

valence remains the same for all elements belonging to same group.... they have two electrons in the outer most shell

valence electrons same

metallic character increases as we go down the group because tendency of losing electrons increases

reactivity increases....
