Document Summary

Chem 111 lecture 13 chapter 7. Explains lots of phenomena of electrons such as: blackbody radiation, photoelectric effect, emission of hydrogen. Help us find the distance between electron orbits. Any extra energy absorbed by the electrons goes into kinetic energy. When energy is absorbed, electrons go up a level, and energy is released to go down a level. 90% probability that current electron model is right. Light bends and interferes with itself and it forms bright spots when shined through a slid. De broglie is a person who have proposed the theorem. Formula: , notice that mass is inverse to the energy. A shell of electron is a certain distance from the center. Also, electrons have spin direction, which are mathematically guessed from the atom formula. Also known as a shell number in which electron resides. The smaller the n the smaller the orbital and energy. It is a sub shell of the given principal shell.
