Platinum
Thorium
Uranium
Zinc
Answer
Thorium, a radioactive metal, was first isolated in 1828 by the Swedish chemist Jöns Jacob Berzelius. It was the first element discovered using chemical rather than alchemical methods and was named after the Norse god Thor due to its strength. Berzelius obtained thorium by reducing thorium tetrachloride with potassium, resulting in the production of pure thorium metal.
