One hundred years of Bohr model

Abstract

In this article I shall present a brief review of the hundred-year young Bohr model of the atom. In particular, I will ¯rst introduce the Thomson and the Rutherford models of atoms, their shortcomings and then discuss in some detail the development of the atomic model by Niels Bohr. Further, I will mention its re¯nements at the hand of Sommerfeld and also its shortcomings. Finally, I will discuss the implication of this model in the development of quantum mechanics.
