Elements sometimes also classified as nonmetals are the metalloids boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and astatine (At). These isotopes can be distilled from the target upon heating it in air. Lithium (from Greek: λίθος, romanized: lithos, lit. Sources: Astatine was first synthesized by Corson, MacKenzie, and Segre at the University of California in 1940 by bombarding bismuth with alpha particles.Astatine may be produced by bombarding bismuth with energetic alpha particles to produce At-209, At-210, and At-211.
