Tantalum
Tantalum (V) Oxide
Tantalum, with the chemical symbol Ta, is the chemical element with the atomic number 73.
The oxidation number of Tantalum in Ta2O5 is +5. In the oxide formula, oxygen has an oxidation number of -2. Since there are two oxygen atoms for every tantalum atom, the oxidation number of Tantalum must be +5 to balance the charges.
Tantalum doesn't exist in pure state in nature.
