How many oxidation states does vanadium have?
four
Vanadium has 5 valence electrons that can be lost. One of the characteristics of transition metal is their ability to adopt multiple oxidation states. Vanadium exhibits four common oxidation states +5, +4, +3, and +2 each of which can be distinguished by its color.
What is phosphorus oxidation number?
Phosphorus is generally considered to bear a 5+ oxidation state, but several lower redox states have been reported, including the toxic gas phosphine.

What is the most common oxidation number of oxygen?
−2
The most common oxidation state of oxygen is −2.
Which has maximum oxidation number?
The highest known oxidation state is +8 in the tetroxides of ruthenium, xenon, osmium, iridium, hassium, and some complexes involving plutonium; the lowest known oxidation state is −4 for some elements in the carbon group.
What element has oxidation number of 1?
Certain elements assume the same oxidation number in different compounds; fluorine, for example, has the oxidation number −1 in all its compounds.
Which oxidation state of vanadium is most stable?
The compounds of vanadium reflect the varied oxidation states possible for this element. Formal oxidation states of +5 to −1 have been found, with the +4 state being the most stable.
Why is vanadium so special?
Vanadium is a medium-hard, steel-blue metal. Although a lesser-known metal, it is quite valuable in the manufacturing industry due to its malleable, ductile and corrosion-resistant qualities. Around 98 percent of mined vanadium ore comes from South Africa, Russia, and China.
What is oxidation number of no?
Answer: The oxidation number of nitrogen is +2.
What is oxidation number of H in cah2?
The oxidation number of hydrogen in H-containing compound is +1.
What are the oxidation numbers of group VIIA?
The elements in Group VIIA often form compounds (such as AlF3, HCl, and ZnBr2) in which the nonmetal has a -1 oxidation number. 9. The sum of the oxidation numbers in a neutral compound is zero. H2O: 2(+1) + (-2) = 0 10. The sum of the oxidation numbers in a polyatomic ion is equal to the charge on the ion.
What is the oxidation number of fluorine in a compound?
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 an element?
The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. Thus, the atoms in O 2, O 3, P 4, S 8, and aluminum metal all have an oxidation number of 0.
What are the oxidation numbers of sulfur atoms?
The oxidation number of the sulfur atom in the SO 4 2-ion must be +6, for example, because the sum of the oxidation numbers of the atoms in this ion must equal -2. SO 4 2- : (+6) + 4(-2) = -2 11.
