| Jan 28, 2014 at 22:10 | comment | added | Nicolau Saker Neto | @leftaroundabout Fair enough. I guess Bohr's model is just often mentioned for historical reasons, to show that models can set limits (even if wrong) and because $v^{1s}_e=Z\alpha c$ is a very simple result. Of course, the Dirac equation itself is also an approximation (a much better one, no doubt). We don't even need a new theory to overturn its conclusions; at some point even more subtle QED effects will become appreciable, and how they will alter the final picture is still unknown, as far as I understand. | |
| Jan 27, 2014 at 22:02 | comment | added | leftaroundabout | With respect to any property these atoms have. The Bohr model simply doesn't work out for anything but 2-body systems, so it can't really apply to atoms other than hydrogen (though it can well apply to $\ce{He}^+$ etc.). | |

| Jan 27, 2014 at 20:28 | comment | added | leftaroundabout | Using the naïve Bohr model of the atom, we run into trouble around $Z = 2$... | |
