The chemical formula for an ionic compound of aluminum and chlorine is:
- AlCl
- ClAl
- AlCl3
- Al3Cl
Hint:
The charge of aluminum is +3.
The correct answer is: AlCl3
- Ionic compounds are made up of metal and non metal.
- In the chemical formula the metal is mentioned first followed by non metal.
- The charge of aluminum is +3 hence, to balance out three chlorine is required as chlorine has -1 charge.
- The chemical formula of aluminum chloride is AlCl3.
