General
The purpose of this section is to go over the basics of Bismuth and for you to get a feel for the element!
Atomic Number (Protons/Electrons)- 83
-Protons- 83 -Neutrons- 126 -Electrons- 83 Atomic Mass (Protons+Neutrons)- 208.98, or 209 when rounded Symbol- Bi Group and Period- Group 15 (Nitrogen or Pnictogens) and Period 6 State of Matter at Room Temp- Solid Element Type- Metal Melting Point- 544.55 K (271.4 C, 520.52 F) This means that Bismuth can be melted in a hot frying pan. Boiling Point- 1837 K (1564 C, 2847 F) |

Isotopes
Even though Bismuth is radioactive, it has one mostly stable isotope, 209, since it decays at an abnormally slow rate. Bismuth 209 is mostly stable, but still can be unstable. Bismuth 209 is the only naturally occurring isotope.
