QUESTION:
Problem 25E
Atomic and Ionic Radii (Section)
Using only the periodic table, arrange each set of atoms in order from largest to smallest: (a) K. Li, Cs; (b) Pb. Sn, Si; (c) F. O. N.
ANSWER:
Step 1 of 3
(a).
Lithium, potassium, and cesium all are IA group elements. On moving down in the IA group, the size of atoms increases as the number of shells increases.
Lithium is present in the second period, potassium is present in the fourth period and cesium is present in the sixth period.
Therefore, the order of atoms from largest to smallest is shown below:
Cs > K >Li
