+1 for Na
-1 for Cl
The oxidation number of nitrogen in the ammonium ion NH4+ is -3, and the oxidation number of hydrogen is +1. In ammonium chloride NH4Cl, the net charge on NH4 is +1 because the chloride ion Cl- has an oxidation number of -1.
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.
Chlorine has an oxidation number of +1 in compounds with metals such as sodium chloride (NaCl) or potassium chloride (KCl).
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 sodium in sodium chloride (NaCl) is +1, and the oxidation number of chloride is -1. Sodium tends to lose one electron to achieve a stable octet, giving it a +1 oxidation state, while chloride tends to gain one electron to achieve a stable octet, resulting in a -1 oxidation state.
The oxidation number of calcium is +2, as it tends to lose two electrons to achieve a stable electron configuration. The oxidation number of chloride is -1, as it tends to gain one electron to achieve a stable electron configuration.
-1 for each Cl, +2 for Sn
A metal and a nonmetal would form an ionic bond. In an ionic compound, a metal ion would have a positive oxidation number equal to its ionic charge. A nonmetal would have a negative oxidation number equal to its ionic charge.Examples:NaCl oxidation numbers: sodium has an oxidation number of +1, chloride has an oxidation number of -1. So the overall charge of NaCl is zero.CaCl2 oxidation numbers: calcium has an oxidation number of +2, the chloride ion has an oxidation of -1. Since there are two chloride ions, the total negative oxidation number is -2, so CaCl2 has an overall charge of zero.
In ICl (iodine chloride), iodine has an oxidation number of +1 because chlorine typically has an oxidation number of -1.
The oxidation number of chlorine in PbCl2 is -1. This is because the overall charge of PbCl2 is 0, and since there are two chlorine atoms in the compound, each chlorine atom must have an oxidation number of -1 to balance with the +2 oxidation number of lead (Pb).
Hydrogen chloride (HCl) is a covalent compound, where hydrogen typically has an oxidation number of +1 and chlorine has an oxidation number of -1.
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.
