Electrons: Mass, discovery & history

Electrons are negatively charged subatomic particles found in the outermost regions of atoms. They are considered to be both partially particle-like and partially wave-like, depending on the scenario, according to West Texas A&M University. Electrons are essentially the reason atoms can interact with other atoms. 

The nucleus of an atom consists of protons and neutrons. Protons are positively charged, neutrons have no charge and electrons are negatively charged, according to the educational website Lumen Learning. The properties of an atom depend on the arrangement of these basic particles.

According to BBC Bitesize, if an atom were the size of Earth, the diameter of the nucleus would be equivalent to just 853 feet (260 meters).
