The model is made of an ionic compound of aluminum and chlorine. Aluminum has an oxidation number of 3 and chlorine has an oxidation number of -1. Based on the evidence, predict the chemical formula, chemical name and properties of the compound between aluminum and chlorine.

                    Chemical Formula: AlCl₃

                    Chemical Name: Aluminium Chloride

                    Properties are given below.

Explanation:

Chemical Formula:

                              Chemical formula depicts the total number of elemants forming a particular compound. It is common that all compounds are neutral in nature despite of the internal charges they contain. As given Aluminium has a + 3 charge while Chlorine has a -1 charge, therefore, to make a neutral compound we will require 3 Cl⁻ ions to neutralize one Al³⁺ ion hence, the chemical formula will be AlCl₃.

Chemical Name:

                              According to rules ionic compounds are named by naming the positive part first followed by negative part. In this case Al³⁺ being is name d first followed by Cl⁻ (remember the -ine in anions is replaced by -ide) hence, this compound will be name as Aluminium Chloride.

Properties:

                 Few physical and chemical properties of AlCl₃ are;

 (i) It melts at 192.4 °C

 (ii) Highly Soluble in water

 (iii) It has a density of  2.48 g/cm³

 (iv) Poor conductor of electricity

 (v) It is used as catalyst in many organic reactions

 (vi) Reacts with silver nitrate to form silver chloride and Aluminium Nitrate
