Fig. 247  a didactic concept
of the structuring of an atom according the suggestion proposed
by Niels Bohr in 1940, displaying the electron configuration
of the Boron element. The elemental atom's particle comprising
the nucleous with 5 protons and 5 neutrons as well as the
outer orbit with 5 electrons. Nowadays, more accurate mathematical
model are used because the particle path, for instance the
electron's position, cannot be measured so accurately to justify
picturing it in an orbit around the nucleous. The mathematical
formulation can forecast the probability of finding the electron
at different distances from the nucleous. This vaguenes about
electronic configuration is the physicists' saga when discribing
the behavior of atom particles.
