Correct Answer:
C. Antineutrino
Correct Answer: Antineutrino
A neutron is converted into a proton through a process known as beta-minus (β⁻) decay. During this nuclear reaction, a neutron inside the atomic nucleus transforms into a proton while emitting an electron, called a beta particle, and an electron antineutrino. This process occurs in unstable radioactive isotopes as they seek greater nuclear stability. Beta decay plays a significant role in nuclear physics, radioactive dating, and the natural decay of many elements. The emitted antineutrino carries away a portion of the energy and momentum released during the decay, ensuring that the fundamental laws of conservation of energy and momentum are satisfied.
