Question
Secondary x-rays released through this process are analyzed in a form of elemental analysis. For 10 points each:
[10e] Name this process in which light is absorbed and reemitted at lower energy. It occurs much faster than phosphorescence.
ANSWER: fluorescence
[10h] Trace divalent atoms of this element in fluorspar contribute to a blue fluorescence. This element is bound to three divalent fod ligands in a prominent lanthanide shift reagent.
ANSWER: europium [or Eu]
[10m] Fluorescence occurs between two of these states whose characteristic multiplicity occurs due to a net zero angular momentum.
ANSWER: singlet states
