Chapter 6: Q68E (page 337)

Question:Based on their positions in the periodic table, predict which has the largest atomic radius: Li, Rb, N, F, I

Short Answer

Expert verified

Rubidium has the largest atomic radius.

Step by step solution

01

describing the trend of change in atomic radius across the periodic table

The atomic radius increases as we go from right to left in the periodic table. The atomic radius increases going from top to bottom (increases in n energy levels and so the distance from the nucleus.

02

predicting which has the largest atomic radius among the given elements

Observing the trends in the periodic table, we can observe that Rubidium is the farthest to the left and farthest down in the periodic table. Hence, it has the largest atomic radius of the given elements.
