Answer:
3 chlorine atoms are needed because each chlorine atom accepts one of Aluminum three valence electrons to obtain a full octet and makes chlorine a negatively charged anion
Step-by-step explanation:
How many chlorine atoms are needed when making Aluminium Chloride?
The formular for aluminium chloride is given as; AlCl3
In the compound, Aluminium has a valency of +3 and the three chlorine atoms each have a valency of +1 to make the compound a neutral compound.
That meas we can represent AlCl3 as Al³⁺ and 3Cl⁻
The correct statement is;
3 chlorine atoms are needed because each chlorine atom accepts one of Aluminum three valence electrons to obtain a full octet and makes chlorine a negatively charged anion
