Chapter 8.1, Problem 3PP

Interpretation Introduction

Interpretation:

The Lewis dot diagram for HCl needs to be determined.

Concept introduction:

Lewis structure is shown by each atom in the molecule using the chemical symbol with the electron. The bond is formed by sharing of electron between the atoms and excess electrons are shown as lone pairs.

Answer to Problem 3PP

After sharing the electron between $Hydrogen\left(H\right)$ and $Chlorine\left(Cl\right)$, valence shells configuration and stable structure can be obtained.

Explanation of Solution

Lewis structure of $HCl.$ :

First write the electron configuration $Hydrogen\left(H\right)$ and $Chlorine\left(Cl\right).$ as follows:

$H\to 1s^1$

$Cl\to 1s^{2}2s^{2}2p^{6}3s^{2}3p^5$

$Hydrogen\left(H\right)$ and $Chlorine\left(Cl\right)$ has $1$ electron and $7$ electrons respectively in their outer most shell.

For the valence shell configuration or stable structure formation, $Hydrogen$ requires $1$ electron and $Chlorine$ also requires $1$ electron.

Thus, the Lewis structure will be:

After sharing the electron between $Hydrogen\left(H\right)$ and $Chlorine\left(Cl\right)$, the stable valence shells configuration and stable structure is formed.

Conclusion

The valence shell configuration can be achieved by sharing the electrons between the atoms.
