Dirac showed that the existence of a magnetic monopole would lead to a quantization of this quantity.
For a baryon, this quantity is related to Baryon number, isospin, and strangeness according to the Gell-Mann-Nishijima formula. Dirac showed that the existence of a magnetic monopole would lead to a quantization of this quantity. A measure for this which is "effectively" felt by a valence electron is used to calculate electronegativity in the Allred-Rochow scale. Mass, angular momentum, and this are the only quantities which characterize black holes according to the "no hair" theorem. The flux at the surface of an arbitrary volume is proportional to this quantity according to Gauss' law for electric fields. For 10 points, identify this property which is carried by electrons and protons but not neutrons.
