Why practical assessments of dislocation density by XRD ignores the texture which apparently affects the result?

As one can read in numerous papers on this matter, the dislocation density is derived from the dependence of peak broadening on the diffraction angle, that is, on considered reflections. Thus, to...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
