Gallium is a chemical element; it has the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [ 13 ] gallium is in group 13 of the periodic table and is similar to the other metals of the group ( aluminium , indium , and thallium ).
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. [7] By far the most popular is the 12 gauge, [7] particularly in the United States. [8] The 20-gauge shotgun is the next most popular size [citation needed], and is popular for upland game hunting. The next ...
These can be used with either lead, bismuth, or steel shot. Older models had factory fixed chokes, and steel shot is not recommended for use with those. Some newer 12 gauge and 20 gauge Citori models have back-bored barrels. These are barrels with slightly larger bore diameters.
[citation needed] Bismuth forms Zintl phases such as NaBi, [153] Rb 7 In 4 Bi 6 [154] and Ba 11 Cd 8 Bi 14. [155] Bailar et al. [156] refer to bismuth as being, 'the least "metallic" metal in its physical properties' given its brittle nature (and possibly) 'the lowest electrical conductivity of all metals.' [n 17] Moscovium is expected to be a ...

The 20-gauge shotgun, also known as 20 bore, is a type of smoothbore shotgun. 20-gauge shotguns have a bore diameter of .615 in (15.6 mm), while the 12-gauge has a bore diameter of .729 in (18.5 mm). [ 2 ] 12-gauge and 20-gauge shotguns are the most popular gauges in the United States .
