Atomic Theory Powerpoint
... • The energy level an electron normally occupies is called its ground state. But it can move to a higher-energy, less-stable level, or shell, by absorbing energy. This higher-energy, lessstable state is called the electron’s excited state. • After it’s done being excited, the electron can return to ...
