In neutronization of the core, a proton and an electron make a neutron and a(n):
A)positron.
B)muon.
C)neutrino.
D)pion.
E)antineutron.

Question

Quizplus · Accepted Answer

In neutronization, a proton absorbs an electron to become a neutron, emitting a neutrino as a byproduct. Therefore, the correct answer is C, neutrino. During neutronization of the core, a proton captures an electron to form a neutron and a neutrino. The other options (A, B, D, E) do not fit the scenario of proton-electron capture to form a neutron.
