Arrange these elements in order of increasing size: Ca, Rb, P, Ge, Sr. (Try doing it without looking at Figure 7.20 and then cheek yourself by looking up the necessary atomic radii.)

Figure 7.20 Atomic radii of s-, p-, and d-block elements (in picometers, pm; 1 pm = 10–12 m). Note the slight change in atomic radii for the transition elements (d block) across a period.
