Electron A negatively charged subatomic

Electron A negatively charged subatomic particle found traveling around the outside of an atom s nucleus in energy levels, or shells. 

Electron A negatively charged subatomic particle that constitutes an insignificant amount of the mass of an atom. 

Electron A negatively charged subatomic particle with almost no mass that can be found outside of the nucleus of an atom of an element. 

The experiments of J. J. Thompson revealed the electron to be a negatively charged subatomic particle of almost no mass. Later scientists described the electron s location and behavior within the atom. By 1932 the most elusive of the big three subatomic particles, the neutron, was shown to exist by Harold Urey, who received a Nobel Prize for his work. The location of the neutral (no charge) neutron is in the nucleus along with the positively charged proton.

Corpuscularian One who believed in matter composed of corpuscles. Electron One of the three basic subatomic components of all elements. It is a negatively charged particle with virtually no mass that orbits the nucleus of an atom. 

To further complicate the subject of subatomic particles, each kind of particle has an antiparticle. For example, for each kind of qnark there is an antiquark of the same mass and spin, but of opposite charge. The first antiparticle to be observed was the positron, an electron with a positive charge. An antiproton is like a proton, but it has a negative charge. Antiparticles can be observed, and molecules of antimatter can even be generated. A positron orbiting an antiproton, for example, is an antihydrogen atom. 

We can deduce the electric charge of subatomic particles by showing how beams of electrons, protons and neutrons behave in electric fields. If we fire a beam of electrons past electrically charged plates, the electrons are deflected (bent) away from the negative plate and towards the positive plate (Figure 2.5a). This shows us that the electrons are negatively charged. 

A subatomic particle that has about the same mass as the hydrogen atom and a negative charge is called (a) a proton (b) a neutron (c) an electron (d) an isotope (e) none of these.
