Radius example sentences

Anion with the greater negative charge will have the larger radius.On moving down the group, for each successive member one extra shell of electrons is added and, therefore, atomic radius is expected to increase.You will appreciate that the ionization enthalpy and atomic radius are closely related properties.The cation with the greater positive charge will have a smaller radius because of the greater attraction of the electrons to the nucleus.Within a family or vertical column of the periodic table, the atomic radius increases regularly with atomic number as illustrated in Figureure 4(b).What are the reasons for the different chemical behaviour of the first member of a group of elements in the s- and p-blocks compared to that of the subsequent members in the same group? The anomalous behaviour is attributed to their small size, large charge/ radius ratio and high electronegativity of the elements.Consequently, the atomic radius of gallium (135 pm) is less than that of aluminium (143 pm).
