Aluminum (Al) is in group 3A and so has 3 valence electrons. It can easily lose these to become Al^3+, so the charge would be +3.
I predict that an ion of sodium will have a charge of plus one.
Aluminum ions carry a charge of three. Al3+.
When an aluminum atom loses its three valence electrons, it becomes positively charged with a charge of +3. This results in an aluminum ion with a 3+ charge.
Aluminum nitrite has a charge of +3, which comes from the aluminum ion (+3) and the nitrite ion (-1).
The charge on a chloride ion (Cl-) is -1. In aluminum chloride (AlCl3), aluminum has a charge of +3, so the overall charge of the compound is neutral.
I predict that an ion of sodium will have a charge of plus one.
Aluminum ions carry a charge of three. Al3+.
The chemical formula for aluminum chloride is AlCl3. This is because the aluminum ion carries a 3+ charge, while the chloride ion carries a 1- charge. To balance the charges, three chloride ions are needed for every one aluminum ion.
When an aluminum atom loses its three valence electrons, it becomes positively charged with a charge of +3. This results in an aluminum ion with a 3+ charge.
A calcium ion (Ca^2+) would have a charge of +2, as it loses two electrons to achieve a stable electron configuration.
Aluminum nitrite has a charge of +3, which comes from the aluminum ion (+3) and the nitrite ion (-1).
The number of electrons are required to predict the charge of the ion.
The charge on a chloride ion (Cl-) is -1. In aluminum chloride (AlCl3), aluminum has a charge of +3, so the overall charge of the compound is neutral.
3+
Aluminum forms an ion with a 3+ charge and is commonly used in the form of aluminum foil as wrapping for leftovers.
Aluminum forms a cation of +3 charge. Sulfite is an anion of -2 charge. To combine, the two would forum aluminum sulfite of the form Al2(SO3)3.
An example of a compound that contains an ion with a 3+ charge is aluminum oxide (Al₂O₃). In this compound, the aluminum ion (Al³⁺) has a +3 charge, while the oxide ion (O²⁻) has a -2 charge. The overall neutral charge of the compound is achieved by combining two aluminum ions with three oxide ions. Other examples include iron(III) chloride (FeCl₃), where the iron ion has a +3 charge.
