The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge. Since opposite charges attract, protons and electrons attract each other.
Electrostatic forces can attract particles together or drive them apart. Oppositely charged particles, like a nucleus (+) and an electron (-), are attracted to one another. Similarly charged particles, like a pair of electrons, repel each other.
In a sense, protons and electrons stick together as much as they can. They simply can't stay together. ... An electron has a lot of kinetic energy. Its constant motion keeps it in orbit around the atomic nucleus, which contains the protons.
