Chapter 8, Problem 8.42QP

Interpretation Introduction

Interpretation:

The size of atoms decreases as we move from left to right using second period of the periodic table elements has to be explained.

Concept Introduction:

• An atomic radius is the distance between the nucleus and outermost electron in an atom. From the atomic radius, the size of atoms can be visualized.
• Coulomb’s law states that the force of attraction between two charged particle which is directly proportional to the product of two charges and inversely proportional to the distance of object’s squares.

$\mathrm{F}=\frac{k{Q}_1{Q}_2}{r^2}$

•  $\text{Li,}\text{Be,}\text{B,}\text{C,}\text{N,}\text{O}\text{and}\text{F}$ are the elements in the second period in the periodic table.
