Role in the atom
Stabilizes the nucleus and prevents protons from repelling each other
Electron Properties
Electrons are subatomic particles that orbit the nucleus of an atom. They have a negative electric charge and contribute to the mass of the atom.
| Property | Value |
|---|---|
| Charge | -1e |
| Mass | 9.1093837 × 10-31 kg |
| Location within the atom | Electron cloud surrounding the nucleus |
| Role in the atom | Participates in chemical reactions and determines the chemical properties of the element |
Interactions between Protons, Neutrons, and Electrons
Within an atom, protons, neutrons, and electrons interact through the electromagnetic force. Protons have a positive charge, while electrons have a negative charge, so they attract each other. Neutrons have no charge, so they do not interact directly with protons or electrons.The
strong nuclear force also plays a role in the interactions between protons and neutrons. This force is much stronger than the electromagnetic force and it overcomes the electrostatic repulsion between protons, keeping the nucleus together.These interactions contribute to the stability of the atom.
The attraction between protons and electrons keeps the electrons in orbit around the nucleus, while the strong nuclear force keeps the protons and neutrons together in the nucleus.
