Answer: The chemical formula of a compound formed between aluminium and chlorine atom will be
AlCl_3

Step-by-step explanation:

Aluminium is the 13th element of the periodic table with electronic configuration of
1s^22s^22p^63s^23p^1

As, this element will easily loose 3 electrons and hence will show an oxidation state of +3.

Chlorine is the 17th element of the periodic table with electronic configuration
1s^22s^22p^63s^23p^5

This element will easily gain 1 electron and shows an oxidation state of -1.

By criss-cross method, the oxidation state of aluminium and chlorine gets exchanged and thus they form the coefficients of the compound.

The compound formed by the combination of aluminium and chlorine will be
AlCl_3

Hence, the chemical formula for the compound will be
AlCl_3
