What Is The Difference Between Thermionic Emission And Photoelectric Emission? What is the difference between thermionic emission and photoelectric emission? During thermionic emission electrons are emitted from metal surface by providing heat energy, whereas, during photoelectric emission light energy is emitted when, electrons are emitted from the surface of metal. Is photoelectric emission and photoelectric

How Does Electron Emission Work? Electron emission is the process when an electron escapes from a metal surface. Every atom has a positively charged nuclear part and negatively charged electrons around it. Sometimes these electrons are loosely bound to the nucleus. Hence, a little push or tap sets these electrons flying out of their orbits.
