Chapter 4.4, Problem 4.4.5SR

Interpretation Introduction

Interpretation: From the given choices the correct choice that contains charges with larger force of attraction should be determined.

Concept Introduction:

Coulombs law: It states that the force of attraction between two point charges is directly proportional to the product of the point charges and inversely proportional the square of the distances between the charges.

$\begin{array}{l}F\propto \frac{Q_1\times Q_2}{d^{\text{2}}}\\ Q_1,Q_2\to \text{Given point charges}\\ d\to \text{distance between the charges}\end{array}$

Valence electron: The electron is considered as valence electron if it present in outermost shell of atom which gets involved in the formation of chemical bond.

Effective nuclear charge: It is the overall positive charge experienced by the outermost electrons present in the atom from the nucleus of the atom.

Screening Effect: The core electrons present near the nucleus shields the outermost electrons (valence electrons) from the charge of the nucleus.
