The property that increases down the periodic table is B. Atomic radius.

Here's why:

A. Ionization energy - This is the energy required to remove an electron from an atom. It generally decreases down a group in the periodic table because the electrons are further from the nucleus and thus, less tightly bound.

B. Atomic radius - This is the size of the atom. As you move down a group in the periodic table, the number of electron shells increases, which means the size of the atom (or atomic radius) increases.

C. Number of valence electrons - This remains constant as you move down a group in the periodic table. Elements in the same group have the same number of valence electrons.

D. Electronegativity - This is a measure of how strongly an atom can attract a bonding pair of electrons. It decreases as you move down a group in the periodic table because the increased number of electron shells shields the positive charge in the nucleus from the valence electrons, reducing the atom's ability to attract electrons.
