Atoms contain electrons orbiting around the nucleus, and those electrons sit inside energy levels (also known as shells). Energy levels are particular orbits, or particular amounts of energy, that electrons are allowed to have. Some examples are shown below:Examples of Atomic Energy Levels: We can draw them as circular orbits (right), or represent them as straight lines, like floors of a hotel (left). Examples of Atomic Energy Levels The electrons in an atom can absorb energy and jump from a…
All matter has a resonant frequency that is represented in this table by their spectral emission when observed via Spectroscopy. As you can imagine, some of these frequencies fall within the visible light spectrum. http://www.fieldtestedsystems.com/ A Microwaved Planet's photo.
