The symbol of a neutron is ‘n’.
A neutron is one of the three main subatomic particles that make up an atom, alongside protons and electrons. It carries no electric charge, which distinguishes it from protons (which are positively charged) and electrons (which are negatively charged). Neutrons play a crucial role in the stability of an atomic nucleus, and their presence helps to balance the repulsive forces between the positively charged protons.
