Atom
The smallest unit of an element, consisting of a nucleus surrounded by electrons.
Nucleus
The central part of an atom, containing protons and neutrons, and is small relative to the atom's size.
Protons
Positively charged subatomic particles found within the nucleus of an atom.
Neutrons
Subatomic particles with no charge, located in the nucleus, acting as a stabilizing force.
Electrons
Negatively charged subatomic particles that orbit the nucleus of an atom.
Nuclear Force
The force that binds protons and neutrons together within the nucleus.
Electrostatic Force
The force that attempts to separate protons and neutrons within the nucleus.
Subatomic Particles
Particles smaller than an atom, including protons, neutrons, and electrons.
Positive Charge
The type of electric charge carried by protons.
Negative Charge
The type of electric charge carried by electrons.
Stability
The condition where nuclear force exceeds electrostatic force, maintaining the nucleus intact.
Element
A substance consisting of atoms with the same number of protons.
