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
