SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. This makes GIS more suitable for certain purposes such as indoor placement, as opposed to air-insulated electrical gear, which takes up considerably more room. 22. 2. O. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein. Two major factors recommend its use: its concentration can be measured with satisfactory accuracy at very low concentrations, and the Earth's atmosphere has a negligible concentration of SF6. [9] It does not react with molten sodium below its boiling point,[10] but reacts exothermically with lithium. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
