It can be distinguished from all other metals by its color—gray-white with a reddish tinge. 1560 o Density 9.75 g/cm 3. 5 Bi sub 0. Bismuth - Protons - Neutrons - Electrons - Electron Configuration. Bismuth is only naturally found as one isotope, which is the almost nonradioactive one.Its radioactivity was predicted by scientists and proven by analyzing the metal. The oxidation of bismuth-tungsten bronzes at 600 and 950°C has been studied using high-resolution electron microscopy at 200 and 500 kV. Its toxicity is much lower than that of its neighbors in the periodic table such as lead, thallium, and antimony. Bismuth(III) oxidation of 3,5-di-substituted-1,2,4-triazolato anions afforded a paddlewheel 1,2,4-triazolato dibismuth complex [L 2 (Bi–Bi)L 2] (L = η 1,η 1-3,5-R 2 tz, R = Ph (3), iPr (4)) with very short Bi(II)–Bi(II) bonds (2.8650(4)−2.8721(3) Å).The reaction involved the intermediates of the organobismuth radical [Bi(R 2 tz) 2]˙ and neutral N-1,2,4-triazolyl radical [3,5-R 2 tz]˙. 5 , Tl sub 0.
