Example Sentences

Wheeler was a legendary scientist that studied under Niels Bohr, who created the most widely recognized model for the atom called the Bohr model.

From Salon

Although modern quantum theory—which Bohr himself helped develop—has shown that the orbits associated with energy levels are more metaphoric than literal, this “Bohr model” of the atom is still essentially accurate.

From Scientific American

Other researchers are testing the limits of the Bohr model by, for example, using powerful X-ray lasers to blast away inner electrons and create 'hollow' atoms.

From Nature

I am on record as championing the Bohr model of the atom when speaking to general audiences with little to no background in physics, in which electrons move about the atomic nucleus in circular orbits.

From Scientific American

But this is a case where the Bohr model just isn’t gonna cut it.

From Scientific American

Bohr magneton Bohr radius
