A method used to characterize the size of fundamental subatomic particles is the Compton wavelength. The Compton wavelength of a particle varies inversely as the mass of the particle. The Compton wavelength of a proton is 0.13, measured in trillionths of a centimeter. The mass of an electron is about 1800 times smaller than the mass of a proton. What is the approximate Compton wavelength of an electron?

Quantum Chemistry

Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned towards the application of physical concepts towards various chemical aspects such as, formation of atoms, chemical structure descriptions, chemical bond strength, hybridization, conjugation etc. Quantum chemistry mainly studies the various states i.e., ground state, excited state, transition states of the individual atoms or molecules taking place during any chemical reaction. The laws of motion explained by various scientists, which are termed as “classical mechanics” were not acceptable in terms of electrons, protons, atoms, light etc. Thus, a new theory named “quantum mechanics” emerged to understand the basic framework of various atomic and subatomic particles.
