Nickel Nuclear Structure

A scientific breakthrough is now provided: Nuclear Stucture of all elements. Iron was the key to understanding that a cubic lattice of baryons is in each atom after boron. Baryons are protons and neutrons. White protons, blue neutrons.

Nickel is ferromagnetic because its nucleus has two coaxial rings of protons.
Nickel is like iron, but with two more protons. It is ferromagnetic.

The link here shows that nickel oxide can be antiferromagnetic.
