WebBismuth is a monoisotopic element and its atomic weight is determined solely by its isotope 209 Bi. The Commission last revised the standard atomic weight of bismuth in 2005 based on the latest Atomic Mass … Bismuth (83Bi) has 41 known isotopes, ranging from Bi to Bi. Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.98040(1). Although bismuth-209 is now known to be radioactive, it has classically been considered to be a stable isotope because it … See more 1. ^ Bi – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits. 3. ^ # – Atomic mass marked #: value and uncertainty derived not from purely experimental … See more Bismuth-213 ( Bi) has a half-life of 45 minutes and decays via alpha emission.

We decided to display two hands, one showing the alchemy symbol for bismuth and the other depicting the solid metal of bismuth itself. We have placed the element symbol (Bi) in one corner as well as the atomic number (83) in another corner of the tile.
