Hence atomic radii of elements increase with the increase in atomic number as we move from top to bottom down a group.

The effect of the progressive addition of a new shell outweighs the effect of increased nuclear charge. (ii) As we move down a group, a new enthalpy shell is added at each succeeding element though the number of electrons in the valence shell the remain the same. (i) Down a group, the nuclear charge goes on increasing. As we move down a group in the periodic table, the atomic radii go on increasing. Theįollowing data pertain to producing one table.Variation of atomic radii in a group.
