Ionic radius (or radii) increases as you move down a group and across a period.
On the periodic table there is no such order of first and second as asked in the question.
if you mean metals ..... for the same valence the radius decreases across a period and increases down a family
the positive ionic radius is smaller than the neutral atomic radius
The smallest element is hydrogen (atomic number = 1). When one electron is added to hydrogen, hydride ion is formed and this is the anion with smallest ionic radius.
The ionic radius is the measure of an atom's ion in a crystal lattice. The value for an ionic radius is typically 30 pm to about 200 pm. An ionic radius is usually measured using x-ray crystallography.

The ionc radius of lithium is bigger compared to beryllium.
A period is a horizontal row in the Periodic Table. So far, there are 7 of them. Each period shows patterns as you go across it(left to right). On of the must-know patterns is that the number of period indicates how many orbitals (or energy levels) the elements in that period have. Other patterns include atomic radius and ionic radius.
The Hydrogen Ion has the smallest ionic radius.
Atoms increase in size as you go down a column and are larger going from right to left across a row.because while going from left to right in a period electrons enter in the same orbit and hence the attraction between the nucleus increasees

ionic charge and ionic radius; the smaller the ionic radius the greater the lattice energy
