* 00 $寸 An electron microscope focuses electrons through magnetic lenses to observe objects at higher magnification than is possible with a light microscope. For any microscope, the smallest object that can be observed is one-half the waveleng th of the radiation used. Thus, for example, the smallest object that can be observed with light of 400.0 nm is 2.00 x 10 m. (a) What is the smallest object observable with an electron microscope using electrons moving at 2.60 x 10 m/s? SE X 10-8 (Enter your answer in scientific notation.) (b) At 2.40 × 107 x 10 -11 (Enter your answer in scientific notation.) -> IIO i # & % 3. 9. 7. 61 alt

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.
