Question

1. Derive expression for bohr's radius of an orbit?​

Answer 1

Answer:

Given that the electrons has an effective mass of 0. 07 me​ (where me​ is mass of the free electron) and the space in which it moves has a permittivity 13ϵ0​, then the radius of the electron's lowermost energy orbit will be close to (The Bohr radius of the hydrogen atom is 0. 53A∘).

hope it helps u !
