Chapter 18, Problem 66E

Interpretation Introduction

Interpretation:The valence electron configuration of Group 6A elements needs to be determined. The property differences between oxygen and polonium needs to be explained.

Concept introduction:Group 6A of periodic table contains elements: $\text{O, S, Se, Te, Po}$ and $\text{Lv}$ . On moving down the group the atomic size increases due to addition of new shells thus, the atomic size increases on moving from O to Lv.
