Which particles are found in the nucleus of an atom?

Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud. Protons and neutrons are bound together to form a nucleus by the nuclear force. read more

The subatomic particles of protons and neutrons are found in the nucleus of an atom. Protons are particles with a positive charge, while neutrons have no charge. Electrons, which have a negative charge, are particles that can found orbiting outside the nucleus of an atom. read more

The particles in the nucleus of an atom are the protons andthe neutrons. We call particles that make up the atomicnucleus nucleons, and this word is just a way to say theparticles that make up an atom's nucleus in an abbreviated manner. read more

The nucleus is the densest part of an atom. Both neutrons and protons have significant mass, while electrons are virtually massless. This model was discovered as a result of the gold foil experiment in 1911 by Ernest Rutherford. read more
