History of Terbium
Who identified it? Terbium was discovered by Carl Gustaf Mosander.
How was it identified? Terbium was identified when the Swedish Chemist Carl Gustaf Mosander when he discovered the element Lanthanum. He was able to obtain two other medal oxides from it; terbium oxide and the other being erbium oxide and he announced there discovery in 1843.
When was it identified? It was identified in 1839
