I've noticed that when reading text that mentions a lot of the '-um' elements -- unranium, plutonium, niobium, platinum -- if the 82nd element crosses my mind, the word that goes through my brain first is "plumbum". A moment later I remember that I almost never call it that, usually thinking of it as "lead".
Too many '-um's in one place, I guess. I'm not sure whether I do the same thing with argentum (which actualy does cross my mind under that name randomly once in a while, but I haven't caught myself spontaneously thinking of silver while reading heavy [pardon] '-um' text so I don't know whether the odds change), but I'm pretty sure I don't do it with aurum. And I haven't noticed a similar effect from reading too many '-en' and '-on' element names in one place.
Yesterday, today's plan for "a day when I've got something planned" turned into "a busy day". (More than one thing scheduled, with one running into travel time for the other, and the possibility of a too-long day.) So I'm probably going to fall farther behind on my LJ reading again.
