Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.

They increase in size.
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
As you move down the periodic table in the noble gases, the atomic size generally increases. This is because the number of energy levels, or electron shells, increases down the group. With each additional energy level, the atomic radius expands, resulting in larger atoms.
As we move down the group, the melting point decreases.
Size typically increases going down a group due to an increasing number of electron shells, where the inner shells reduce the attractive forces of the nucleus and repel the electrons in the outer shell .
The reactivity of a non metal decreases as you move down a group. This is because the size of the atomic radius increases and when the distance to the nucleus increases, the force of attraction decreases. Electrons are not pulled as strongly to larger atoms, and so larger atoms are not as reactive.
it's socks, eh?
Down the group, size increases. Because number of shells increases.
atomic number increases
Down a group, the atomic size (energy level / shells) increases.

yes
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.

Atomic size increases down the group. The number of shells increases causing more atomic radius.
