Noble gases end with -on.
Boron, carbon, silicon, and iron are not noble gases, so should be renamed. (But it is fun to pronounce them as if they rhymed with the noble gases. Carbon sounds like "car bomb".)
First try: mechanically replace -on with -ium (keeping the British happy): borium, carbium, silicium, irium. However, borium sounds identical to bohrium and very similar to barium. Irium sounds very similar to iridium. Carbium sounds similar to carbonium (carbon complex cation). The c in silicon becomes soft, though we could work around that with silickium.
Renaming iron to ferrum, simply restoring its Latin name, would make it consistent with its element symbol Fe.
We could similarly replace -on with -um for the others: borum, carbum, silicum.
However, given the importance of carbon for life, surely we can come up with a new, fitting name for it. Perhaps biogen.
Similarly silicon and electronics.
Helium is a noble gas but does not end in -on, so it too should be renamed. Perhaps helion.
