Final answer:
The correct notation for a neutron is n, which indicates a neutral particle with a mass number of 1. Unlike protons (p^+) and electrons (e^-), the neutron does not have a charge symbol in its notation.
Step-by-step explanation:
The notation for a neutron in nuclear reactions and equations is represented by the letter n. The neutron is electrically neutral, which means it has no charge. Its mass number is 1 because it contains one nucleon (neutral particles in the nucleus of an atom), hence the notation does not have a charge symbol associated with it, in contrast to other particles such as the electron (e^-) with a mass number of 0 and a charge of -1 or the proton (p^+) with a mass number of 1 and a charge of +1. In beta decay, neutrons can transform into a proton and an electron to achieve stability.
The notation of a neutron is represented as n. It is a particle that has no charge and is found in the nucleus of an atom. Neutrons play a crucial role in determining the stability of an atomic nucleus, as they help to balance the positive charge of protons. It is important to note that the mass number of a neutron is 1, and it does not have an atomic number.
