What is the Lewis Dot Structure?
In electron dot structures, the number of valence electrons for an element is represented by dots. According to the periodic chart, valence electrons possess the highest energy level.
The element symbol is used to symbolize an electron dot structure, with dots being added clockwise beginning at the top of the symbol until the desired number of valence electrons is obtained. The number of available electrons is restricted to eight.

Lewis Dot Structure of Aluminium
Group IIIA on the Periodic Table, aluminium has three valence electrons. It is represented by the letter Al. A single atom of aluminum contains thirteen electrons. The first orbit has two electrons, the second orbit contains eight electrons, and the third orbit contains three electrons. Therefore, it has three dots surrounding it in its Lewis structure.
Properties of Aluminium
The following are some of aluminium’s physical properties:
- The element has high reactivity. It has roughly a third of the rigidity and density of steel.
- Magnesium is the only commercial metal with a lower density than aluminium.
- Aluminium is an odorless and tasteless metal with a silvery-white hue. Aluminium alloys become more malleable and pliable as their silicon content rises.
- The crystal structure of aluminum is face-centered and cubic.
- Aluminum has excellent corrosion resistance.
Uses of Aluminium
- As castings, it is utilized in rail, truck, and vehicle transportation.
- It is utilized in the packaging sector.
- Al(III) compounds are produced through the reactions of Al metal with oxidants.
- Using aluminon, aluminum can be discovered through qualitative analysis.
Example of Compounds by Aluminium
Aluminium Trifluoride
Fluorine (F) can bond with aluminum as well (Al). Fluorine atoms can readily utilize the three additional electrons that aluminium possesses. Since aluminum has three valence electrons, it can form bonds with three fluorine atoms. The chemical formula is AlF3.
Aluminium trichloride
Aluminum and chlorine (Cl) can also create a bond (Al). Aluminium has three additional electrons that chlorine atoms can readily employ to form bonds. AlCl3 is the chemical formula of the substance.
Aluminium Phosphide
Phosphorus (P) and aluminium (Al) are likewise capable of bonding. Aluminum possesses three additional electrons, but each phosphorus atom must acquire three electrons. Its chemical formula is AlP3.
