  4. Energy level - Wikipedia

    en.wikipedia.org/wiki/Energy_level

    An increase in energy level from E 1 to E 2 resulting from absorption of a photon represented by the red squiggly arrow, and whose energy is h ν. A decrease in energy level from E 2 to E 1 resulting in emission of a photon represented by the red squiggly arrow, and whose energy is h ν.

  5. Degenerate energy levels - Wikipedia

    en.wikipedia.org/wiki/Degenerate_energy_levels

    The energy levels in the hydrogen atom depend only on the principal quantum number n. For a given n , all the states corresponding to ℓ = 0 , … , n − 1 {\displaystyle \ell =0,\ldots ,n-1} have the same energy and are degenerate.

  6. Atomic clock - Wikipedia

    en.wikipedia.org/wiki/Atomic_clock

    Whereas a hydrogen atom moves at 1,600 m/s at room temperature and a nitrogen atom moves at 510 m/s, a caesium atom moves at a much slower speed of 130 m/s due to its greater mass. [ 69 ] [ 10 ] The hyperfine frequency of caesium (~9.19 GHz) is also higher than other elements such as rubidium (~6.8 GHz) and hydrogen (~1.4 GHz). [ 10 ]

    Pekka Pyykkö divides these superactinides into three series: a 5g series (elements 121 to 138), an 8p 1/2 series (elements 139 to 140), and a 6f series (elements 141 to 155), also noting that there would be a great deal of overlapping between energy levels and that the 6f, 7d, or 8p 1/2 orbitals could well also be occupied in the early ...

    The iconic windows informed the asymmetric shape of Toledano & Chan’s design. And just as the Breuer Building is largely free from ornamentation, the faces of both the B/1 and the B/1M are void ...

  9. Subatomic scale - Wikipedia

    en.wikipedia.org/wiki/Subatomic_scale

    The subatomic scale is the domain of physical size that encompasses objects smaller than an atom.It is the scale at which the atomic constituents, such as the nucleus containing protons and neutrons, and the electrons in their orbitals, become apparent.
