-1
The oxidation number of chlorine in AlCl4 is -1. Since aluminum has an oxidation number of +3, the overall charge of the AlCl4 ion is -1, meaning each chlorine atom has an oxidation number of -1 to balance the charge.
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 oxidation number of P in PCl3 is +3. This is because chlorine typically has an oxidation number of -1, and there are three chlorine atoms in PCl3, giving a total charge of -3. To balance this charge, the oxidation number of P must be +3.
The oxidation number for iron in ferric chloride (FeCl3) is +3. Chlorine has an oxidation number of -1, and since there are three chlorine atoms in ferric chloride, the overall charge must be balanced by the iron atom having an oxidation number of +3.
The oxidation number of chlorite (ClO2-) is +3. In this ion, the oxygen has an oxidation number of -2 and since there are two oxygen atoms, that gives a total of -4. To balance the charge of -1 for the chlorite ion, the chlorine atom must have an oxidation number of +3.

The oxidation number of chlorite (ClO2-) is +3. In this ion, the oxygen has an oxidation number of -2 and since there are two oxygen atoms, that gives a total of -4. To balance the charge of -1 for the chlorite ion, the chlorine atom must have an oxidation number of +3.
No, the oxidation number of CaCl2 is not 3. In CaCl2, calcium (Ca) has an oxidation state of +2, and each chlorine atom (Cl) has an oxidation state of -1. This combination allows for the compound to have a neutral charge.
In NCl3, chlorine has an oxidation number of -1. The sum of the oxidation numbers in a compound is equal to the overall charge of the compound, which in this case is 0. Since there is only one nitrogen atom in NCl3, its oxidation number must be +3 to balance out the -3 from the three chlorine atoms.
In HClO2, the oxidation number of hydrogen (H) is +1 since it is typically +1 in compounds, the oxidation number of chlorine (Cl) is +3, and the oxidation number of oxygen (O) is -2. The sum of the oxidation numbers in a compound must equal zero, so in HClO2, the oxidation number of chlorine (+3) is balanced by the oxidation numbers of hydrogen (+1) and oxygen (-2).
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
The oxidation number for Cl in KClO3 is +5. This is because oxygen has an oxidation number of -2 and potassium has an oxidation number of +1, so the total oxidation numbers must add up to zero for the compound.
Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.
The oxidation state of Cl in ClO2 is +3. This is determined by assigning oxygen an oxidation state of -2 and knowing that the overall charge of the compound is 0. Since there are two oxygen atoms with an oxidation state of -2 each, the oxidation state of Cl must be +3 to balance it out.
