Vanadium is a chemical element; it has symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal . The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer ( passivation ) somewhat stabilizes the free metal against further oxidation .
Cp 2 V 2 (CO) 5 featuring a pair of semi-bridging CO ligands. [15] Organovanadium chemistry is the chemistry of organometallic compounds containing a carbon (C) to vanadium (V) chemical bond. [16] Organovanadium compounds find only minor use as reagents in organic synthesis but are significant for polymer chemistry as catalysts. [17]
Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V 2 O 5. Commonly known as vanadium pentoxide, it is a dark yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent.

A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
Vanadium phosphates are inorganic compounds with the formula VO x PO 4 as well related hydrates with the formula VO x PO 4 (H 2 O) n. Some of these compounds are used commercially as catalysts for oxidation reactions.
Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t 2g orbitals.
Vanadium(III) sulfate is the inorganic compound with the formula V 2 (SO 4) 3. It is a pale yellow solid that is stable to air, in contrast to most vanadium(III) compounds. It slowly dissolves in water to give the green aquo complex [V(H 2 O) 6] 3+. The compound is prepared by treating V 2 O 5 in sulfuric acid with elemental sulfur: [2]
