| Dec 3, 2015 at 22:56 | comment | added | DavePhD | @Mithoron but the same number 137 (from the fine structure constant) is the limit for Dirac or Sommerfeld relativistic theory. You get imaginary numbers in the energy equation above 137. Other changes in the model beyond considering relativity are needed to avoid the 137 limit. | |
| Dec 3, 2015 at 22:38 | comment | added | Mithoron | @DavePhD Geez, he's talking about Bohr. With Dirac you'd have oscillating ground state not "exceeding c". and with more precise analysis you have problem at about 173, but of another kind en.wikipedia.org/wiki/… | |

| Dec 3, 2015 at 22:20 | comment | added | Karl | Already for elements in the fifth (or even earlier?) period, calculations of the inner electronic structure make no sense at all if relativity is not taken into account. | |
| Dec 3, 2015 at 22:19 | comment | added | DavePhD | @Mithoron they could be relativistic: "Dirac showed that there are no stable electron orbits for more than 137 electrons" physics.info/atomic-models | |

| Dec 3, 2015 at 22:07 | comment | added | Mithoron | The article you cite is bad, and those calculation couldn't be relativistic | |
| Dec 3, 2015 at 21:43 | comment | added | Jon Custer | Electrons, under quantum mechanics, do not have 'speeds' in the Bohr sense. But, if you asking if relativistic quantum mechanics is possible, it most certainly is. | |
