In chemistry and atomic physics, an <b>electron</b> shell, or a principal <b>energy level</b>, 
may be thought ... The physical chemist Gilbert Lewis was responsible for <b>much</b> 
of the early development of the theory of the ... The <b>electron</b> shells are labeled K, 
L, M, N, O, P, and Q; or 1, 2, <b>3</b>, 4, 5, 6, and 7; going from innermost shell outwards
. A quantum mechanical system or particle that is bound—that is, confined 
spatially—can only take on certain discrete values of energy, called <b>energy levels</b>
. This contrasts with classical particles, which can have any amount of energy. 
The term is commonly used for the <b>energy levels</b> of <b>electrons</b> in atoms, ions, ... 
The shells correspond with the principal quantum numbers (n = 1, 2, <b>3</b>, 4 . The <b>3</b> → 2 transition depicted here produces the first line of the Balmer series, 
and for hydrogen (Z = 1) it results in a photon of wavelength 656 nm (red light). In 
atomic physics, the Rutherford–Bohr model or Bohr model, presented by Niels 
Bohr and ... An <b>electron</b> in the lowest <b>energy level</b> of hydrogen (n = 1) therefore 
has about&nbsp;... In atomic physics, Hund&#39;s rules refers to a set of rules that German physicist 
Friedrich Hund ... The rules assume that the repulsion between the outer

shift all the <b>energy levels</b> together. ... The superscript <b>3</b> is the value of the 
multiplicity = 2S + 1 = <b>3</b>. H-alpha (Hα) is a specific deep-red visible spectral line in the Balmer series with 
a wavelength of 656.28 nm in air; it occurs when a hydrogen <b>electron</b> falls from its 
third to second lowest <b>energy level</b>. ... Since it takes nearly as <b>much</b> energy to
