1. Understand the Valence Electrons:
* Hydrogen (H): Has 1 valence electron.
* Chlorine (Cl): Has 7 valence electrons.
2. Draw the Atoms:
* Write the symbol for hydrogen (H) and chlorine (Cl) with spaces between them.
3. Place Valence Electrons:
* Represent valence electrons as dots around the atomic symbols.
* Start placing dots individually on the four sides of each atom.
* Once you have four dots, start pairing them up.
4. Form the Bond:
* Hydrogen needs one more electron to achieve a stable electron configuration (like helium).
* Chlorine needs one more electron to achieve a stable electron configuration (like argon).
* They share one electron each, forming a single covalent bond.
Electron Dot Formula for HCl:
```
H • Cl :

```
Key Points:
* The shared pair of electrons in the middle represents the single covalent bond.
* Both hydrogen and chlorine now have a full outer shell of electrons.
