Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic and antimony. Elemental bismuth occurs naturally, and its sulfide and oxide forms are important commercial ores. The free element is 86% as dense as lead. It is a brittle metal with a silvery-whit…

WebBismuth is a chemical element with atomic number 83 which means there are 83 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of … Web2) Atomic radii and ionic radii. Atomic radii, as well as ionic radii, increase if we go from the upper elements to the lower elements. It is because of adding an extra electronic orbital. But in the case of arsenic and bismuth, this increment is not that much because of the addition of d and f orbitals. 3) Ionization enthalpy WebIt is the Rapid addition of neutrons to existing nuclei.C. It is a process that can produce elements up to #83 - Bismuth.D. It is known as nuclear fusion and the formation of new … folding motorized skateboard with backpack
