Condensed electronic configuration of:
Al: 1s² 2s² 2p⁶ 3s² 3p¹
F: 1s² 2s² 2p⁵
The bond between Al and F is Ionic bond. It is classified as an ionic compound due to the larger electronegativity gap between the two atoms that comprise the complex.
Aluminium fluoride is the compound formed from these two atoms.
Aluminium fluoride is a colourless chemical compound having the molecular formula AlF3.
Physical properties:
- Aluminium fluoride has the appearance of white powder or granules.
- It has an odourless property.
- At a temperature of 25°C, its solubility in water is approximately.559g/100 mL.
- This molecule is very marginally soluble in alkalis and acids.
- In nature, aluminium fluoride is non-flammable.
The formula of their compound if AlF₃.
Aluminium is a group 13 element on the periodic table.
Hence, the valence electrons present in aluminium is 3.
Fluorine is a group 17 element on the periodic table.
Hence, the valence electrons present in fluorine is 7 .
Hence in a AlF3 molecule,
Valence electrons given by Aluminium (Al) atom = 3
Valence electrons given by each Fluorine (F) atom = 7
So, total number of Valence electrons in AlF3 molecule = 3 + 7(3) = 24
