Vanadium (atomic symbol: V, atomic number: 23) is a Block D, Group 5, Period 4 element with an atomic weight of 50.9415.  Elemental VanadiumIt is a hard, ductile transition metal that is primarily used as a steel additive and in alloys such as Titanium-6AL-4V, which is composed of titanium, aluminum, and vanadium and is the most common titanium alloy commercially produced.Vanadium is a d-block transition metal that exists in nature in multiple oxidation states, each of which imparts a distinctive color to its salts: purple/lavender/violet (+2), green (+3), blue (+4), and yellow (+5).
