A silver-white, soft metal known for its brilliant shine, Niobium is prone to oxidation and gradual corrosion when exposed to air. It dissolves easily in dilute acids and liquid ammonia and reacts slowly with water. The divalent salt appears green, is water-soluble, and releases hydrogen at a slow pace. Its oxide is white. This malleable metal boasts a lustrous, silvery-white finish.
