Thus, light waves can be characterized by their wavelength, frequency, and intensity. The more intense light is, the more energy it carries. The absorption spectrum of atomic hydrogen has a line at 121.6 nm. The magnetic properties of electrons arise from a property called spin . All electrons have spin of the same magnitude, but electron spin can have a positive or negative sign depending on which way the electron responds to a magnet.
Electrons have wave properties.
Each atomic energy level can be associated with a specific three-dimensional atomic orbital Their energies are quantized. Quantization of energy is a property of bound electrons. A bound electron is one held in a specific region of space by coulombic attraction for a nucleus in an atom or molecule. Because of their wave properties, electrons are always spread out rather than localized in one particular place. In a universe subject to uncertainty, many things cannot be measured exactly, and it is never possible to predict with certainty exactly what will occur next.
