The existence of the electron showed that the 2,000-year-old conception of the atom as a homogeneous Answer: Electron. Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force. Electrons are negatively charged subatomic particles found in the outermost regions of atoms. It is positively charged if it loses electron from it. WebA negatively charged subatomic particle that is distributed around the nucleus in an atom is called a(n) _____. Which part of an atom is positively charged, and which part is negatively charged? Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. It shows the electron as a particle orbiting the nucleus, similar to the way that planets orbit the sun. Thomson's scientific achievements didn't go unnoticed. proton.

The number of electrons and protons in an atom are exactly the same. Which subatomic particle can be absent from an atom? D) Proton. Atomic Theory Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus. Simple View of Atomic Because protons and neutrons are so much more massive than electrons, almost all of the mass of any atom comes from the nucleus, which contains all of the neutrons and protons.
