I think that Pb is +2 and I is -1. Mrs. Anderson
The oxidation number of lead (Pb) in PbI2 is +2. Iodine (I) typically has an oxidation number of -1 in compounds. Since there are two iodine atoms in PbI2, the total negative charge contributed by iodine is -2. This balances with the +2 charge of lead to make PbI2 neutral.
A metal typically has only positive oxidation numbers, while a nonmetal can have both positive and negative oxidation numbers. Metals tend to lose electrons (positive oxidation numbers) to form cations, while nonmetals can gain or lose electrons to form a variety of oxidation states.
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
The sum of the oxidation numbers for P2O5 is zero. In P2O5, the oxidation number for phosphorus is +5, and each oxygen atom has an oxidation number of -2. Since there are five oxygen atoms, the total sum of the oxidation numbers is 2(+5) + 5(-2) = 0.
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
The oxidation number of lead (Pb) in PbI2 is +2. Iodine (I) typically has an oxidation number of -1 in compounds. Since there are two iodine atoms in PbI2, the total negative charge contributed by iodine is -2. This balances with the +2 charge of lead to make PbI2 neutral.
It would be: PbI2

No, the can only have positive oxidation numbers
The sum of the oxidation numbers for P2O5 is zero. In P2O5, the oxidation number for phosphorus is +5, and each oxygen atom has an oxidation number of -2. Since there are five oxygen atoms, the total sum of the oxidation numbers is 2(+5) + 5(-2) = 0.

Lead(II) iodide (PbI2) is typically a yellow colored solid.
The simple answer is not always. The stoicheometry deals with oxidation numbers only in redox reactions. The ratio of the change in oxidation numbers is straightly its stoicheometry.
The sum of the oxidation numbers in a neutral compound is equal to zero. This is because in a neutral compound, the total positive oxidation numbers are balanced by the total negative oxidation numbers to give a net charge of zero.
The sum of oxidation numbers in a neutral compound is always zero, as the charges balance out. In polyatomic ions, the sum of oxidation numbers equals the charge of the ion. When determining oxidation numbers, rules such as assigning elements in their elemental state an oxidation number of zero and hydrogen an oxidation number of +1 are typically followed.
No, not all metals have two oxidation numbers. Some metals may have multiple oxidation numbers depending on the bonding situation and the compounds they form.
