Going down the group, atomic radius is increasing, and the shielding of the valence electron ( very important in metallic bonding ) is also increasing.

This can be used to explain a number of periodic trends such as atomic radius, first ionization energy ( IE ), electronegativity, and oxidizing.
33.
The atomic radius of helium is so small that shale, which is effective in trapping methane, allows the helium to migrate upward through the shale pores.
34.
When zinc lacks electron donating ligands it is unable to obtain coordination saturation, which is a consequence of the large atomic radius and low electron deficiency of zinc.
35.
Atoms of phosphorus, sulfur, and chlorine are about an �ngstr�m in covalent radius, while a hydrogen atom is about half an �ngstr�m; see atomic radius.
36.
The noble gas atoms, like atoms in most groups, increase steadily in atomic radius from one nucleus and are therefore not held as tightly together by the atom.
37.
Because it has the largest atomic radius among the halogens, iodine has the lowest first ionisation energy, lowest electron affinity, lowest electronegativity and lowest reactivity of the halogens.
38.
The actual size of the atoms is dictated by the atomic radius and such considerations, based ultimately on the effective size of the electron orbitals that form the basis of chemistry.
39.
The number of smaller halogens that can bond to a large central halogen is guided by the ratio of the atomic radius of the larger halogen over the atomic radius of the smaller halogen.
40.
The number of smaller halogens that can bond to a large central halogen is guided by the ratio of the atomic radius of the larger halogen over the atomic radius of the smaller halogen.
