protonsA new model of cosmic ray albedo neutron flux above the atmosphere, based on Geant4 simulation of atomic and nuclear interactions, is used to calculate radiation belt neutron-decay source functions for electrons and protons. The model covers albedo neutron energies from 0 to 100 GeV. ...
Finally, recent experiments on the deflection of protons and alpha particles in collision with an atomic nucleus seem to lend support to the idea of a magnetic field in the vicinity of a nucleus.doi:10.1038/119237b0ALLENH. SNatureAllen, H. S. "Spinning Electrons and Protons." Nature 119 ...
The Bohr model shows the atom as a central nucleus containing protons and neutrons, with the electrons in circularorbitalsat specific distances from the nucleus, as illustrated in Figure 1. These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons...
(Electrons do actually combine with protons in the extreme conditions associated with neutron stars.) Niels Bohr built the first quantum mechanical model of the atom, which demanded that electrons occupy definite orbits. Light is emitted or absorbed when an electron jumps between levels....
It is worth noting that in reality atoms are not built by adding protons and electrons one at a time and that this method is merely an aid for us to understand the end result. As seen in the Figure above , the energies of the sublevels in different principal energy levels eventually ...
(Li)contains three electrons in orbit around a nucleus that includes three protons(Z=3), and Bohr's model can be used for the doubly charged positive ion of lithium(Li2^(+))that results when two electrons are removed from the neutral atom, leaving only one electron to orbit the nucleus...
and has more electrons than protons. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. If an ion...

We analyze the origin of the gamma-ray flux from the Fermi Bubbles (FBs) in the framework of the hadronic model in which gamma-rays are produced by collisions of relativistic protons with the protons of the background plasma in the Galactic halo. It is assumed in this model that the ...
