118 is the number of chemical elements in the first 7 periods of the periodic table, and it is the number of elements which are ever expected to be most useful to humans. As a result, chemical element names can be used as note names in 118edo.  
118 is the number of chemical elements in the first 7 periods of the periodic table, and it is the number of elements which are ever expected to be most useful to humans. As a result, chemical element names can be used as note names in 118edo. In addition, such a notation is succinct and provides a fine one-to-one correspondence between notes and their names, as opposed to extending small scales into large EDOs which create excessive labels. Some may argue that other notations. like [[Ups and Downs Notation|ups and downs]] favor [[12edo]] or [[5L 2s|the diatonic scale]], while the chemical notation system has no such issue.  


Interval names can be made using the suffix "-ide", as to how a 2-atom molecule would be named in chemistry. For example, fluoride for limma, chloride for 17 steps, strontide for classical major third. These are appended to the initial note. For example, an interval of 17 steps on the 1st note would be called hydrogen chloride, a limma on the 11th note would be called sodium fluoride. Classical minor 6th on 29th note would be called copper mercuride, etc.
However, chemical notation's properties can also be a disadvantage - it requires a certain level of knowledge of chemistry, or at least memorizing the names of the elements of the periodic table. In addition, since all the notes are separately named, it does not reflect the harmonic structure of 118edo.  
 
It should be noted that vast majority of these intervals do not make chemical sense, such as apotome on the 9th note, which would be chlorine sodiide. In real life, this is impossible, as flow of electrons is always to chlorine, not from it.
