The XENON collaboration observes an excess events in its XENON1T dark matter experiment
Where is the excess of events coming from? A tiny residual amount of tritium (a hydrogen atom with one proton and two neutrons)? Or a sign of something more exciting—such as the existence of a new particle known as the solar axion or the indication of previously unknown properties of neutrinos?

SOLVED:"Inert" xenon actually forms many compounds, especially with highly electronegative fluorine. The ΔHf^∘ values for xenon difluoride, tetrafluoride, and hexafluoride are -105,-284, and -402 kJ / mol , respectively. Find the average bond energy of the Xe-F bonds in each fluoride.
