WebAug 24, 2014 · As the particles — in this case protons and neutrons — form nuclei, the nuclei have a net spin value. Sometimes the spin can cancel out as the numbers of protons and neutrons increase in a nucleus. NMR can be used to observe nuclei having: an odd atomic number (number of protons), or an odd mass number (number of protons and neutrons) http://www.chem.ucla.edu/~harding/IGOC/N/nuclear_spin_state.html

As the name suggests, spin was originally conceived as the rotation of a particle around some axis. While the question of whether elementary particles actually rotate is ambiguous (as they appear point-like), this picture is correct insofar as spin obeys the same mathematical laws as quantized angular momenta do; in particular, spin implies that the particle's phase changes with angle. On the other hand, spin has some peculiar properties that distinguish it from orbital angul… WebThe positively charged protons in the nucleus stabilize the electronic orbitals by electrostatic attraction between the positive charges of the protons and the negative charges of the electrons. So the further away the electron is from the nucleus, the greater the energy it has. ... They called this the spin quantum number, or m s.
