Articles on the study of matter and energy at the most fundamental level.
The discovery of a temperature seen by an accelerated fiducial observer adds a new dimension to the equivalence principle. Identical…
As the incident photon energy increases, the likelihood that it will undergo Photoelectric Effect decreases and the Compton Effect also…
Regarded as one of the greatest discoveries, Niels Bohr’s original quantum theory of spectra was one of the most revolutionary…
This property of atomic electrons was discovered through experimentation. The close observation of spectral lines revealed that each line was…
Bohr’s correspondence principle states that predictions of quantum theory must correspond to the predictions of classical physics in the region…
The magnetic quantum number for an electron classifies which orientation its subshell shape is pointed. The “lobes” for subshells point…
The exclusion principle states that no two electrons in an atom can have the same set of quantum numbers i.e.…
A shell is made up of subshells. Subshells are regions of space where electron “clouds” are allowed to exist, and…
Symbolized by the letter n, this number describes the shell that an electron resides in. An electron “shell” is a…
Compton Effect was a key experiment that provided the most direct evidence for the particle nature of radiation. Arthur Holly…
