Niobium density

Niobium Facts, Symbol, Discovery, Properties, Uses

Density of Niobium is 8.57g/cm 3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/ Niobium is also a fairly dense element and it is this density that might account for its apparent rarity. Occurring at only twenty parts per million, it is 33 rd in the hall of fame of most common elements in the Earth's crust. This surprisingly low value might arise from the 'missing' niobium sinking to the Earth's core during the planet's.
