Quantum Numbers “Where are the Electrons?”
... n tells the distance from the nucleus and the energy of an electron in that main energy level (electrons in n=1 are closest to the nucleus and have the lowest energy) There can be more than one orbital in a main energy level. The total number of orbitals that exist in a given energy level is e ...

... The time taken between the diver taking off and entering water is 1.34 s. The diver can step on the springboard harder, so that more elastic potential energy is stored in the springboard. Then by the law of conservation of energy, the diver can jump higher and he will have longer time to finish his ...

No Evidence for Particles
... Subjectively, it seems awkward to have a two-tiered scheme in which wavefunction-based quantum mechanics determines all the numbers, while particles—absent from the quantum mathematics—supply the structure necessary for agreement with our perceptions. This suggests we take a close look to see if par ...
