Atoms can exist without electrons, Matter is build out of neutrons, protons (+) and electrons (-). Matter becomes stable only if it is electrically neutral. WebExperimental evidence indicates that, within an atom, a small nucleus, which generally contains both protons and neutrons, is surrounded by a swarm, or cloud, of electrons. The fundamental properties of these subatomic particles are their weight and electrical charge.
WebAn atom consists of electrons, protons, neutrons. protons are positively charged and electrons are equally negatively charged. The charge of the electrons stabilizes the charge of protons. Why are neutrons present? My question is why physicists believe that neutrons are also present when the charge of electrons and protons can stabilize each other.
