What is the symbol for aluminium chloride?

[aadaasdark8072]

May I correct a bit in the question? Elements have symbols Aluminum Chloride is a chemical compound Hence it has no symbol but a chemical formula
Chemical formula for aluminium Chloride is
AlCl 3
REASON—-
Electronic configuration of Aluminium atom is 2,8,3
So there 3 electrons in its outermost orbit
Electronic configuration of Chlorine atom
is 2,8,7
So there are 7 electrons in its outermost orbit Each of them has a tendancy to have 8 electrons (octet) in its outermost orbit Hence they give or take electrons
Here aluminum is the donor Chlorine is the
acceptor Aluminum atom has 3 electrons to give and a Chlorine atom can accept only a single electron,Hence three Chlorine atoms are required to accept three electrons given by the aluminum atom Therefore three Chlorine atoms react with a single aluminum atom Hence the chemical formula of aluminium Chloride is AlCl3
The answer is given in detail looking at the question and that too for beginners

The molecular formula for Aluminium chloride is AlCl3. It is the main compound of aluminium and chloride. It is white in colour but it often contaminated by iron chloride which changes its colour to yellow.

AlCl3 has three different structures. Solid AlCl3 is a sheet-like layered cubic close packed layers. The Al centers exhibit octahedral geometry, with the central aluminum ion surrounded by six water ligand molecules.

But it usually exists as a dimer (Al2Cl6) with tetracoordinate aluminium.

The Molecular Formula of Aluminium Chloride is AlCl3

A breif on how the molecular formula of Aluminium Chloride is determined.

Aluminum has 3 electrons in it’s valence shell so it is willing to give electrons rather than to accept ones, while chlorine has 7 electron in it’s valence shell which makes it tend to accept electrons. As one chlorine atom will only be able to accept only 1 electron to conplete its valence shell, the Aluminum will require 3 chlorine atoms to get it self stabilised. Therefore Aluminium shares one electron with each of the 3 chlorine atoms and hence the molecular formula AlCl3. Where Al will possess positive three(+3) charge and each of Chlorine atom will posses negative one (-1) charge.
