Write the expression for Bohr's radius in hydrogen atom?

Write down the expression for the radii of orbits of hydrogen atom.Calculate the radius of the smallest orbit.

State Bohr’s postulates for atomic modeland using them derive an expression for the radius of nth orbit in hydrogen atom and show that radii are in the ratio 1 : 4 : 9 :16 :..........

On the basis of Bohr's atomic model,find an expression for radius of nth orbit of a hydrogen atom.

What is Bohr's radius?

The kinetic and potential energy (in eV) of electron present in third Bohr's orbit of hydrogen atom are respectively :

Obtain the first Bohr radius of muonic hydrogen atom [i.e., an atom in which a negatively charged muon (mu) of mass about 207m_e orbits around a proton].

State Bohr’s postulates for atomic model and derive an expression for radius of the electron in an orbit.

The gravitational attraction between electron and proton in a hydrogen atom is weaker than the coulomb attraction by a factor of about 10^ -40 . An alternative way of looking at this fact is to estimate the radius of the first Bohr orbit of a hydrogen atom if the electron and proton were bound by gravitational attraction. You will find the answer interesting.
