Jöns Jacob Berzelius, in discussing the work of Davy, Gay-Lussac, and Thénard in 1824, identifies boron as an element.
Berzelius is in this year the first to prepare a pure form of amorphous silicon; he names it silicium.
The same year, Berzelius isolates zirconium metal in impure form, which, even when ninety-nine percent pure, is hard and brittle.
