Which of the following statements has been punctuated correctly; if neither is punctuated correctly, let me know. you, much! a) the pauli exclusion principle: assertion, that, no two electrons in an  atom, can be, at the same time, in the same state, or  configuration, proposed (1925) by the austrian physicist, wolfgang pauli, to account for the observed patterns of light emission from atoms. the exclusion principle, subsequently, has been generalized to include a whole class of particles, of which, the  electron,  is only one member. b) the pauli exclusion principle, assertion that no two electrons in an atom can be at the same time in the same state or configuration, proposed (1925) by the austrian physicist wolfgang pauli to account for the observed patterns of light emission from atoms. the exclusion principle subsequently has been generalized to include a whole class of particles of which the electron is only one member.
