Atomic radii among transition metals

Figure 8.10 Periodicity of atomic radius. A plot of atomio radius vs. atomic numberforthe elements in Periods 1 through 6 shows a periodic change the radius generally decreases through a period to the noble gas [Group 8A(18) purple] and then increases suddenly to the next alkali metal [Group 1 A(1) brown]. Deviation from the general deorease occurs among the transition elements.
