This is a gas compound. Chlorine shows +4 as the oxidation number.
In HgCl2, mercury's oxidation number is 2+ and chlorine's is 1-.
-1 is found in chlorides. But chlorine can have other oxidation numbers up to +7 in its compounds.
Oxidation number of chlorine is +7. oxidation number of O is -2.
In GeCl2 germanium is in the 2+ oxidation state and chlorine is in the 2- oxidation state.
-1 (most common)
-1
-1
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
