Niels Bohr won a Nobel Prize for the idea that an atom is a small, positively charged nucleus surrounded by orbiting electrons. He also contributed to quantum theory.

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 went on to make enormous contributions to physics and, like Rutherford, to train a new generation of physicists. But his atomic model remains the best known work of a very long career.

To mark the 127th birthday of physicist Niels Bohr, Google has created a doodle to showcase his contributions to science and features his Bohr atomic model.

It's a simplistic model, yet provides insights into atoms and chemical properties, and this year marks 100 years since the model was first proposed by Danish physicist Niels Bohr. The idea that ...

Bohr proposed an atomic structure, known as the Bohr model, that placed the atom's neutral nucleus in the center of orbiting, charged electrons.
