+3 for Al, -1 for Br
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. This is because each chlorine atom has an oxidation number of -1, and there are three chlorine atoms bonded to the aluminum atom, resulting in a total charge of -3 for the chlorine atoms. For the compound to be neutral, the aluminum atom must have an oxidation number of +3.
In MgBr2, the magnesium ion (Mg) has an oxidation number of +2, while the bromide ion (Br) has an oxidation number of -1.
In magnesium bromide (MgBr2), magnesium has an oxidation number of +2 and each bromine atom has an oxidation number of -1. This is because magnesium typically forms 2+ cations, while bromine forms 1- anions.
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
AlBr3 is the formula for aluminum (III) bromide.
magnesium bromide
The oxidation number of Al is +3.
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. This is because each chlorine atom has an oxidation number of -1, and there are three chlorine atoms bonded to the aluminum atom, resulting in a total charge of -3 for the chlorine atoms. For the compound to be neutral, the aluminum atom must have an oxidation number of +3.
The colour of aluminum bromide is white.
In MgBr2, the magnesium ion (Mg) has an oxidation number of +2, while the bromide ion (Br) has an oxidation number of -1.
In magnesium bromide (MgBr2), magnesium has an oxidation number of +2 and each bromine atom has an oxidation number of -1. This is because magnesium typically forms 2+ cations, while bromine forms 1- anions.
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
+3 for each Al; +4 for each C; -2 for each O
The oxidation number of Br- is -1. Bromine typically has an oxidation state of -1 when it forms an ion by gaining one electron.
In the compound Al₂O₃, aluminum has an oxidation number of +3, and oxygen has an oxidation number of -2. This gives a total charge of zero for the compound, as it should be electrically neutral.
