|Paris—Paul-Émile Lecoq de Boisbaudran, Eugène-Anatole Demarçay elements|
- William Crookes in London
- and Paul-Émile Lecoq de Boisbaudran in Paris
- had noted its spectral lines
- but Eugène-Anatole Demarçay got credit
- for discovering europium
- because he had more special characters in his name.
- Seriously, Lecoq already had a sample of it
- contaminating his samarium,
- which he had previously discovered.
- But Demarçay isolated the contamination
- and so he got to name it after Europe,
- thinking that Europe was not just a fiction.
Atomic number 63
- This rare
- rare earth
- can make
- a red phosphor
- and a blue one.
- Chemistry isn’t random.
- Europium atoms are similar in size and charge
- to the calcium contained in plagioclase,
- so if a magma crystalizes into plagioclase
- then it captures more europium.
- Biology seems more random.
- Who’s to say whether the second child
- will die of old age or cancer?
- Will he inherit his father’s strength
- or his mother’s good looks?
