The neutrino was proposed by Pauli to overcome the apparent violation of which of the following conservation laws in beta decay?

Question

Quizplus · Accepted Answer

In beta decay, the electron (or positron) energy and momentum do not add up to the energy and momentum of the parent and daughter nuclei, violating the conservation of both energy and momentum. By proposing the existence of a neutral, weakly interacting particle (the neutrino), Pauli was able to explain the missing energy and momentum as carried away by the neutrino, thus restoring the conservation of energy and momentum. The conservation of charge is not violated in beta decay, as the electron and proton charge cancel each other out in the nucleus.
