depends. in square planar complexes, it's usually +1 but in octahendral complexes it's +3
With the molecular formula Au2Cl6, the name gold trichloride is a simplification, referring to the empirical formula, AuCl3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold compounds
The oxidation number of BH4 in the compound is -1.
The oxidation number for carbon in CHI3 compound is -2. In CHI3, iodine has an oxidation number of -1 and hydrogen has an oxidation number of +1, which allows carbon to have an oxidation number of -2 to balance the overall charge of the compound.
The oxidation number of an uncombined element is zero. The sum of oxidation numbers in a neutral compound is zero. Group 1 metals have an oxidation number of +1, and Group 2 metals have an oxidation number of +2. Oxygen usually has an oxidation number of -2. Hydrogen usually has an oxidation number of +1. Fluorine always has an oxidation number of -1. The more electronegative element in a binary compound is assigned its typical oxidation number. Within a polyatomic ion, the sum of oxidation numbers equals the charge of the ion. In a coordination complex, the oxidation number of the metal ion is equal to the overall charge of the complex. Remember that these rules are guidelines and may vary based on the specific compound or situation.
In the compound H2S, hydrogen has an oxidation number of +1, and sulfur has an oxidation number of -2.
