Protium. The start of the start. The true start of the list of all isotopes in elemental and numerical order. The dream of the Aspie - the way of the taxonomist.
The word Protium makes me think of protons. I guess that is the origin of the name. But is it even a good name - does it convey the essence of the element within? I think hydrogen-1 is a bit more refined as a name. 1H if you want to get technical and who doesn’t? The generic way is H-1 and I’ll settle there for now because it is the easiest to write.
H-1; are you really all you can be? I don’t think so. They gave you a number and a name, but you’re still not satisfied.
