A neutron is a subatomic particle found packed inside the nucleus of an atom alongside protons. Unlike protons, which are positive, or electrons, which are negative, a neutron has no electrical charge, making it completely neutral. Neutrons are very important because they act like "nuclear glue," helping to hold the positively charged protons together so the nucleus doesn't fly apart.

Even though they don't have a charge, neutrons have about the same mass as a proton, meaning they contribute significantly to the total weight of an atom. The number of neutrons in an atom can sometimes vary even within the same element; these different versions of the same atom are called isotopes. Without neutrons, the nuclei of most atoms would be unstable and could not exist!
