The subatomic particle that is neutral is the Neutron. (An) electron is a negatively charged particle
According to modern atomic theory, the proton can't move from one energy level to another
With the work of the English chemist John Dalton, the current atomic theory, which has continuously undergone refining, started to blossom at the beginning of the 19th century.
The modern atomic theory holds that atoms are no longer indestructible and now contain electrons, protons, neutrons, and other sub-particles. Isotopes are variations of an element's atoms that can exist.
The concepts of atoms and how they create matter are established by current atomic theory. Atoms are composed of negatively charged electrons revolving around a core nucleus made up of electrically neutral neutrons and more massive positively charged protons.
