Sommerfeld extension of bohr theory

WebCorrect option is A) The value of Bohr radius for hydrogen atom is 0.529×10 −8 cm. It can also be written as 0.529×10 −10 m which corresponds to 0.529 A o. Was this answer helpful? WebMay 29, 2024 · Just as Sommerfeld’s extension of Bohr’s model had opened a route toward quantum mechanics, his semiclassical electron theory (1927) paved the way for the quantum theory of solids. However, it would be misleading to sum up his contributions only as a hinge between classical and modern physics—a transition that deserves critical …
