Blue toruses = 7 protons
Red toruses = electrons, yes, 3 nuclear electrons
Atomic number of Be7 = protons (7) - nuclear electrons (3) = (4), with structure D He3 D
Beryllium 7 transform by K electron capture of
Beryllium 7
and Lithium 7
produced: Be7 + e- = Li7
(K electron capture can only occur at the end of the nuclear nanotube, NOT into the central part of proton rod of nucleus. The s electrons of K shell are positioned along the axis of the nucleus.)
