WebbIn atomic physics, the Bohr model of the atom (also known as the Rutherford-Bohr model) is the modern model of the hydrogen atom introduced by Danish physicist Niels Bohr. The Bohr model adopted Planck’s quantum hypothesis, and he proposed a model in which the electrons of an atom were assumed to orbit the nucleus but could only do so in a finite … WebbNiels Bohr proposed a model of the atom and a model of the chemical bond.
