Final answer:
In Bohr's model of the hydrogen atom, the electron orbits the proton in a circular orbit of radius 0.529×10⁻¹⁰ m. This model helps to explain the emission spectra of hydrogen.
Step-by-step explanation:
In Bohr's model of the hydrogen atom, the electron moves in a circular orbit around the proton. The electron's orbit has a specific radius, which is 0.529×10⁻¹⁰ m in the case of the hydrogen atom. This circular orbit is maintained by the attractive Coulomb force between the electron and the proton.
It is important to note that Bohr's model is a simplified representation of the hydrogen atom and does not fully account for the quantum mechanical nature of electrons. However, it was significant in explaining the emission spectra of hydrogen and laid the groundwork for further developments in atomic theory.
