Ionic radii `"________"` with increases in atomic number in a period and `"_______"` in a group.

With the increases in atomic number in period

With the increase in atomic numbers the atomic radii go on decreasing in case of

Generally the atomic and ionic radii increase with increase in atomic number down the group. But the atomic size of aluminium and gallium is almost the same. This is because
