... Although apparently satisfactory Lewis electron-dot structures of N2, O2, and F2 can be drawn, the same is not true with Li2, Be2, B2, and C2, which violate the octet rule. In addition, the Lewis structure of O2 predicts a double-bonded, diamagnetic (all electrons paired) molecule ( O O ), but exper ...

X-ray fluorescence
X-ray fluorescence (XRF) is the emission of characteristic ""secondary"" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
