The radius will increase, this is because as you go down there are more electrons and they are put into progressivly larger orbitals so in effect the raidus increases.

Decreases. Look at the images under atomic radius, on wikipedia.
As you go down group 1, the atomic number and atomic mass increase. Electronegtivity decreases and atomic radius increases.
Atomic radius increases down the group. This is because of the increase in number of shells.
because new shell are being added as we move down the group and the electron is being far away from the nucleus so the attraction bettween the nucleus and the electron is smaller It means that their is a less use of ionisation energy . Therefore, atomic radius increase down the group.

Yes. The atomic radius increases down the group. This is because number of shells increases down the group.
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.

atomic radius decreases from bottom to top of the periodic table.

As you look down a group you notice that the atomic radius increases or becomes larger.
The atomic numbers of the elements down a group increase. this means, more electrons. More electrons mean more shells. More shells mean larger radius. Larger radius is nothing but larger size. Thus, the number of electrons or shells is the reason why the size of the atom of elements increase down the group.
Atomic radius (or size) increases as you move down a group from top to bottom. This is because with each spot you move down, you go up a period, which means you add an energy level to the atom. This translates to electrons being farther and farther from the nucleus (which also lowers electronegativity and ionization energy.)
This happens only down a group. Let us consider Lithium and sodium which belong to the same group, Group 1. In a Lithium atom which has 3 electrons, the last electron enters the 2s orbital or the L-shell. The next element of the same group, Sodium, has 11 electrons. the last electron enters the 3s orbital or the M-shell. It is now clear that as you move down the group, a new shell gets added which means the atom is getting bigger. And this is because the atomic number increases down the group which is why Lithium (at. no. 3) is before Sodium (at. no. 11). This trend is observed in every group.
As we move down the group, the melting point decreases.
