Atomic spectra - discussed above Periodic behavior of elements - elements with similar properties had similar atomic spectra. Each electron orbit of the same size or energy (shell) could only hold so many electrons. For example, the first shell could hold two electrons, the second could hold ei...

Among the 11 newly identified crystals, polymorphs of alkali metals Na, K, and Cs have DFT calculated S1111 − S1122 − 2S2323 values much more negative than that of Mo, but they are all hypothetical crystals that have not been experimentally synthesized yet. Five polymorphs are indeed ...
