Chapter 8, Problem 64
Arrange these elements in order of decreasing atomic radius: Cs, Pb, Sb, Se, S.
Verified step by step guidance1
Identify the periodic trend for atomic radius: Atomic radius generally increases as you move down a group and decreases as you move across a period from left to right.
Locate each element on the periodic table: Cs (Cesium), Pb (Lead), Sb (Antimony), Se (Selenium), and S (Sulfur).
Determine the group and period for each element: Cs is in Group 1, Period 6; Pb is in Group 14, Period 6; Sb is in Group 15, Period 5; Se is in Group 16, Period 4; S is in Group 16, Period 3.
Compare the elements based on their positions: Elements in higher periods generally have larger atomic radii. Elements in the same period decrease in atomic radius from left to right.
Arrange the elements in order of decreasing atomic radius based on their positions and periodic trends.
