Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

“Wallis couldn’t have possibly known [the trend] would show up in the hydrogen atom because no-one knew about the hydrogen atom then,” Friedmann says. She adds that, while the formula could have been ...

Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly ...

The shortcomings of the Bohr model. The Bohr model seemed to work pretty well for atoms with only one electron. But apart from hydrogen, all other atoms in the periodic table have more, some many ...

The Bohr model successfully predicts hydrogen energy levels with good accuracy, but it’s a wrong in every other way. The first problem with the Bohr model is that, like the solar system, it describes ...

Bohr’s Model of an Atom: Students get to know the Bohr’s Model of an Atom. Find out what are its limitations and the postulates it is based on.

Bohr was able to use his new theory to successfully explain the regularities in the pattern of light emitted from hot hydrogen gas, both in the laboratory and in the atmospheres of stars near and far.

ONE of the difficulties which confronts Bohr's structure of the hydrogen atom is the fact that hydrogen, on his hypothesis, should be paramagnetic, whereas it is, like the majority of the simple ...
