... Hence, when a cation is formed from an atom of a transition metal, electrons are always removed first from the ns orbital and then from the (n−1)d orbitals if necessary. Since the metal ion has a +3 charge, three electrons have been removed. Since the 4s subshell is less stable than the 3d, two elec ...

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.
