the valence of aluminum is +3 and the valence of chlorine is -1. the formula for aluminum chloride is correctly written as?
How many Chloride ions at -1 charge will equal one +3?
Aluminium chloride is a whitish solid. Formula: AlCl3.
To determine the correct formula for aluminum chloride, we need to consider the valence of each element involved.
The valence of aluminum is +3, meaning it has three extra electrons to lose in order to achieve a stable electron configuration. On the other hand, the valence of chlorine is -1, indicating that it needs one extra electron to achieve stability.
Since aluminum has a valence of +3 and chlorine has a valence of -1, we can combine them in a way that balances their charges. To do this, we need to determine the number of chloride ions needed to balance the charge of one aluminum ion.
Since the valence of an aluminum ion is +3 and the valence of a chloride ion is -1, we can see that three chloride ions with a charge of -1 each will combine with one aluminum ion with a charge of +3.
Therefore, the correct formula for aluminum chloride is AlCl3.
