Vanadium er et grunnstoff som har atomnummer 23 og atomsymbol V. Det er et sølvhvitt metall som lett kan valses til tynne folier og trekkes til tynne tråder. Vanadium er det første grunnstoffet i gruppe 5 i periodesystemet. Det vanligste ionet er V5+. Mindre
Ionic Compounds . Ionic compounds have a [+] cation and a [-] anion. We use the Principle of Charge Neutrality, that is, for an ionic compound to be stable its chemical formula MUST BE NEUTRAL. So you do not need to state the number of cations and anions, you only need to state what they are (and what their charge is).

Vanadium is a natural element in the earth. It is a white to gray metal, often found as crystals. It has no particular odor. Vanadium occurs naturally in fuel oils and coal. In the environment it is usually combined with other elements such as oxygen, sodium, sulfur, or chloride. The forms of vanadium most likely to be found at waste sites are not well known.
