-3
17. In the phosphate ion, the oxidation number of phosphorous is+5. The sum of the oxidation numbers in PO43-, a polyatomic ion, is -3, the charge of the ion. We assign -2 as the oxidation number of each O and x as the oxidation number of P and write the following equation: x + 4(-2) = -3….

What is the name of Fe3(PO3)2?
Accordingly , the name of Fe3 (PO3)2 is iron (II)phosphite. b. Ba (NO2)2. Barium is an element in group IIA ; thus it has a fixed charge of +2. NO2- has one less oxygen than nitrate, NO3- , nitrate; so its name is nitrite, thus : Covalent compounds are formed when two or more nonmetals combine.
What are the rules for assigning oxidation numbers?
Rules for assigning oxidation numbers. The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion.
What is the oxidation number of free elements in a compound?
The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion. Fluorine in compounds is always assigned an oxidation number of -1. The alkali metals (group I) always have an oxidation number of +1. The alkaline earth metals (group II) are always assigned an oxidation number of +2.
What is the oxidation number of oxygen in Group 2?
The alkaline earth metals (group II) are always assigned an oxidation number of +2. Oxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2) where it is -1 and in compounds with fluorine (OF 2) where it is +2.
