443589226 | de Broglie Relation | Lamda= h/ m(mass)v | |
443589227 | Louis de Broglie | Reasone that if light exhibits particle aspects, then perhaps particles of matter show characteristics of waves under the proper circumstances | |
443589228 | Quantum Mechanics | Aka Wave mechanics the branch of physics that mathmatically describes the wave properties of of submicroscopic particles | |
443589229 | Uncertainty Principle | A relation that states that the product of the uncertainty in position and the uncertainty in momentum of a particle can be no smaller then plans constant divided by 4 pi. | |
443589230 | atomic orbital | a wave function for an electron in an atom | |
443589231 | principal quantum number (N) | this quantum number is the one on which the energy of an electron in an atom principally depends; it can have an positive vaule: 1, 2, 3, and so on. | |
