Table 9.2 does not include francium because none of francium’s isotopes are stable. Predict the values of the entries for Fr in Table 9.2. Predict the nature of the products of the reaction of Fr with: 

(a) Water, 

(b) Oxygen, and 

(c) Chlorine.

TABLE 9.2 = Summary of Periodic Properties Trend Moving Down a Column Property Atomic Radii First lonization Energy Electron Affinity Metallic Character Increasing Decreasing No definite trend Increasing Reason for Trend Moving Down Size of outermost occupied orbital increases Outermost electrons further away from nucleus (and therefore easier to remove) lonization energy decreases Trend Moving Across a Row Decreasing Increasing Decreasing (more negative) Decreasing Reason for Trend Moving Across Effective nuclear charge increases Effective nuclear charge increases Effective nuclear charge increases lonization energy increases
