Bohr explained in his model of atom that atom consists of a central region of positively charged protons and neutrally charged neutrons together called nucleus and the electrons revolve around it in discrete orbits

actually bohr is main scientist who postulate the atomic structure. they give following concept which helpful in atomic structure.
1) electron move around the nucleus in circular path called orbit , each having a particular amount of energy .the energy of orbit increases as the distance of orbit from nucleus increases .
2) an electron doesn't radiate energy as long as it revolves in a particular orbit. it make a transition from one orbit to another, when it emits or absorb energy.
3) the angular momentum associated with an orbit is integral multiple of h/2pi
i.e. mvr=nh/2pi.
4) during revolution in an orbit, the necessary centripetal force is provided by the electrostatic force of attraction between electron and nucleus.
so,
mv^2/r=KZe^2/r^2
