Chapter 6: Q67E (page 337)

Question: Based on their positions in the periodic table, predict which has the smallest atomic radius: Mg, Sr, Si, Cl, I.

Short Answer

Expert verified

Chlorine has the smallest atomic radius.

Step by step solution

01

discussing the trend of 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 among the given has the smallest atomic radius

Observing the trends in the periodic table, we can observe that chlorine has farthest on the right and highest on the periodic table. Hence, it has the smallest atomic radius.
