Explanation:
The given compound is:
AlCl₃
- ionic formula - it is a combination between a metal and non - metal with an electronegativity difference greater than 0.7
- 3 chlorine atoms - from the compound, we see that the compound is made up of 1 aluminum atom and 3 chlorine atoms.
- Aluminum is the cation
- Chlorine is the anion
A cation is the positively charge specie and the anion is the negatively charged one.
Al³⁺ + 3Cl⁻ → AlCl₃
