The oxidation number for an element by itself is 0. The oxidation number Np could have in a compound depends on what other elements it is bonded with. One common online Periodic Table lists the most common oxidation number for Np in compounds as +5, and less common states as +3, +4, +6, and +7.

What is neptunium's color?
Neptunium typically appears as a silvery metal, but it can also exhibit different colors depending on its oxidation state; for example, neptunium dioxide (NpO2) is dark brown to black in color.
What are the chemical properties of neptunium?
Neptunium is a radioactive actinide element with properties similar to uranium. It can exist in multiple oxidation states, such as +3, +4, +5, +6, and +7. Neptunium compounds are typically soluble in water and exhibit a variety of colors depending on the oxidation state.
Is neptunium corrosive?
Neptunium is dangerous due to it's radioactivity- it is similar to Uranium or Plutonium. It is likely to be chemically poisonous, but the radiation effects outweigh the chemical hazards. Neptunium is rarely found in a pure state, and results from decay of other radioactive materials, such as Plutonium and Americium.
Does a metal or nonmetal have both positive and negative oxidation numbers?
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.
What is THE common oxidation number for tantalum?
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Do metals have both positive and negative oxidation numbers?
No, the can only have positive oxidation numbers
What is the sum of the oxidation numbers for P2O5?
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.
What is the oxidation numbers in PO34?
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
Does oxidation numbers take into account stoicheometery?
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.
What is the sum of the oxidation numbers in a neutral compound equal to?
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.
Sum of oxidation numbers charge in a compound?
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.
Do all metals have two oxidation numbers?
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.
