Document Summary

All about atoms: ~l and ~mu are coupled. In this chapter we will discuss the properties of atoms. We are summarizing around 100 years of research in physics that had transform our understanding of atoms. Every electron in a atom has: an orbital angular momentum. 1 properties of atoms: an orbital dipole moment, atoms are stable. The have not changed in billions of years: atoms combine with each other. Atoms make com- plex arrangements called molecules in all shapes and forms: atoms are put together systematically. This means that atoms elements are constructed following an or- dered process: atoms emit and absorb light. We know that atoms can take certain energy states, property known as energy quantization. When an atom changes its energy it will either emit a photon or absorb one. The frequency of the light can be determined by this equation. hf = ehigh elow. (1: atoms have angular momentum and magnetism.
