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 don't d-orbitals split themselves, why does it take a ligand? why don't protons from ligand repel nucleus split d-orbitals?

why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the...

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...

Dear Ayesha Sabir, use one of the controlled polymerization techniques, such as ATRP and RAFT/MADIX. If you can't, do fractionation of the product you have. Literature about polymer fractionation is available via simple search. My Regards

Ayesha Sabir

Thanks for your response Abdelkader BOUAZIZ
