Ch.8 - Periodic Properties of the Elements

Problem 64

Previous problem

Chapter 8, Problem 64

Arrange these elements in order of decreasing atomic radius: Cs, Pb, Sb, Se, S.

Verified step by step guidance

1

<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.>
