Tantalizing: something you really want but probably cannot get.
...named after Tantalus, the son of Zeus who was condemned to stand in water under a fruit tree, but the fruit and water were always just out of reach. He had a daughter, Niobe, and son, Pelops.
Tantalum, the material, was named because it could not be easily dissolved in any acid, unlike most other metals. Despite knowing of the element's existence, researchers could not isolate the chemical in tantalite samples for decades, as it was always bound to this other material---later called niobium, although one guy thought there were two or more other metals and wanted to call the other one pelopium. Nope; all niobium!
Sadly, tantalum became something of a semi-professional metal outside of capacitors, and even there ceramics and aluminums are preferred for one reason or another---usually cost. It was good for bulb filaments until tungsten displaced it. It was great for fountain pen nibs but not as great as iridium and osmium. It doesn't help with alloying because it embrittles. Other biologically inert materials are usually chosen over tantalum for implants. It could be a refractory ceramic but tantalum carbide is not as heat resistant as hafnium carbide.
It also has weird nuclear properties, where someone will probably look back in a the distant future and remark, "damn, that awesome commercial application of nuclear tantalum evaded us for centuries! What a fitting name!"
I never connected until just now that I should probably avoid breathing in any of the magic smoke when a tantalum capacitor explodes.
