The chemical symbol Ta was proposed by Jöns Jakob Berzelius in 1814. Berzelius was also the first person to produce elementary tantalum. However, Heinrich Rose recognized that the tantalum produced in this way actually only consisted of 50% tantalum. In 1844, Rose succeeded in proving that ...
Tantalum is a chemical element with Ta as its symbol. It belongs to group 5, periodic number 6 of the periodic table. Its atomic number is 73. Tantalum is a silvery metal that is soft in its pure form. It is a strong and ductile metal and at temperatures below 150°C (302°F), ...
