Uranium is the ninety-second element of the periodic system. The atomic ground state is designated 5L 0 6 in spectroscopic notation and has a 1s 2 2s 2 2p
Chemical zoning within mineral grains can be leveraged to determine the maximum length of time the grains could have remained at magmatic temperatures without being compositionally homogenized by element diffusion16. This study constrains the highest temperature portion of the Mg-suite cooling path by ...
models that rely on an atomistic decomposition of the energy must have representations for the environment of each separate element (for example, see refs.6,26). To improve the sampling represented in the training set for resorcinol, we can leverage overlap with configurational spaces sampled by ...
indicating that the measured concentrations are well explained by the source contribution estimates. Theχ2value is the weighted sum of squares of the differences between the measured and calculated element concentrations. Ideally, there should be no difference, resulting inχ2of 0. A largeχ2(>4.0...
There are 38 isotopes of zinc, ranging in atomic weights from Zn-54 to Zn-83.Just four of these are stable, and those four, plus one naturally radioactive isotope (Zn-70) that has a very long half-life (5×10+14years), make up the element’s existence onEarth. Their proportional ...
