Bismuth
Post-transition Metal • Period 6 • Group 15
*Half-life ~1.9 × 10¹⁹ yr — effectively stable
Electron Configuration
Noble-gas shorthand: [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³ — valence electrons highlighted in blue.
Oxidation States
The +3 state dominates due to the inert-pair effect — the 6s² electrons resist ionization at this period.
Summary
Bismuth (symbol Bi, atomic number 83) is a heavy post-transition metal in Group 15 of the periodic table and is known for its unusually low toxicity among heavy metals. Its naturally occurring isotope ²⁰⁹Bi is radioactive but has an extraordinarily long half-life. This reference card displays every key property — from atomic mass and electron configuration to oxidation states, thermal data, and industrial uses — in a clean, searchable layout.
