In this and subsequent chapters, we build on this information to explain why certain chemical changes occur and others do not. The process of Radiation emits energy. If the electron is in an energy eigenstate, then its energy is equal to the eigenvalue. It would have to have a different energy after emission, so it would need to be in a different eigenstate, with a different eigenvalue. Depends on what its eigenstate of. So, one finds the level and subtracts the full layer below. If there are multiple orbitals of equal energy, they will be filled with one electron in each energy level before a second electron is added. 7 What is valence what is its importance in chemistry? The two electrons associated with a pair of hydrogen atoms are placed in the lowest energy, or bonding, molecular orbital, as shown in the figure below. 8 Why does placing an electron in an antibonding orbital make a molecule less stable?
