Chlorine has 7 valence electrons and requires one more electron to complete the octet. Hence it has an oxidation number of -1.
But, it should be noted that chlorine show positive oxidation numbers (up to +7) also in its compounds
The oxidation number of chlorine in the compound PbCl is -1. Each chlorine atom in PbCl has an oxidation number of -1, as lead has a fixed oxidation number of +2.
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 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 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).
The oxidation number of chlorine in MgCl2 is -1. Magnesium is a group 2 element with an oxidation number of +2, and since the compound is neutral, the total oxidation number of the two chlorine atoms must equal -2, making the oxidation number of each chlorine atom -1.
The oxidation number of chlorine in the compound PbCl is -1. Each chlorine atom in PbCl has an oxidation number of -1, as lead has a fixed oxidation number of +2.

The oxidation number of chlorine in KCl is -1. This is because potassium (K) has an oxidation number of +1 and the overall compound is neutral, so the oxidation number of chlorine must be -1 to balance the charge.
The oxidation number of chlorine can vary depending on the compound it is in. It can have an oxidation number of -1 in most compounds, but it can also have positive oxidation numbers in compounds like ClO4- where it has an oxidation number of +7.
-1 is most common in chlorides. However chlorine can exhibit oxidation numbers up to +7 in its compounds.
To find the oxidation number of chlorine, consider that chlorine typically has an oxidation number of -1 in its compounds. However, in certain situations, such as when bonded with oxygen or other halogens, chlorine can have different oxidation states. It's important to follow the usual oxidation number rules and balance the charges in the compound to determine the oxidation number of chlorine.
In hydrochloric acid (HCl), the oxidation number of hydrogen is +1 and the oxidation number of chlorine is -1.
In CI4, the oxidation number of chlorine is -1. Since there are 4 chlorine atoms, the total oxidation number contributed by chlorine is -1 x 4 = -4. To neutralize the charge, the oxidation number for the central atom must be +4.
-1 is found in chlorides. But chlorine can have other oxidation numbers up to +7 in its compounds.
