  2. Bismuth - Wikipedia

    en.wikipedia.org/wiki/Bismuth

    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 ...

  3. Shot (pellet) - Wikipedia

    en.wikipedia.org/wiki/Shot_(pellet)

    Lead shot. Shot is a collective term for small spheres or pellets, often made of lead.These have been projected from slings since ancient times and were the original projectiles for shotguns and are still fired primarily from shotguns and grenade launchers, while they are less commonly used in riot guns.

    en.wikipedia.org/wiki/Shotgun_cartridge

    The .410 bore is the smallest shotgun size which is widely available commercially in the United States. For size comparison purposes, the .410, when measured by gauge, would be around 67- or 68-gauge (it is 67.62-gauge), The .410 is often mistakenly assigned 36-gauge. The 36 gauge had a 0.506" bore. Reloading components are still available.

  5. Isotopes of bismuth - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_bismuth

    Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.980 40 (1). Although bismuth-209 is now known to be radioactive, it has classically been considered to be a stable isotope because it has a half-life of approximately 2.01×10 19 years, which is more than a billion ...

    left-to-right: .410 bore, 28 gauge, 20 gauge, and 12 gauge shotgun shells. The six most common shotgun gauges, in descending order of size, are the 10 gauge, 12 gauge, 16 gauge, 20 gauge, 28 gauge, and .410 bore. [3] By far the most popular is the 12 gauge, [3] particularly in the United States. [4]

  8. Bismuth compounds - Wikipedia

    en.wikipedia.org/wiki/Bismuth_compounds

    Unlike the lighter pnictogens nitrogen, phosphorus, and arsenic, but similar to antimony, bismuth does not form a stable hydride. Bismuth hydride, bismuthine (BiH 3), is an endothermic compound that spontaneously decomposes at room temperature. It is stable only below −60 °C. [5] Bismuthides are intermetallic compounds between bismuth and ...
