# How are protons, neutrons, and electrons similar?

Protons are massive, positively charged nuclear particles. Neutrons are massive, neutrally charged nuclear particles. You are no doubt aware that together, the protons and neutrons form the nucleus, the massive elemental core, which is held together by the strong nuclear force, a short range force that is greater than the electrostatic force of repulsion. So much for $\text{nucular physics}$.
