after thomson and rutherford , bohr gave his atomic model concept into picture . 
acc to him 
1- in a atom , nucleaus is fixed at the centre and all the masses are concentrated inside the nucleaus . 
2- the electrons can revolve in some specific orbit around the nucleaus . 
3- those orbits can be called as specific for which the angular momentum is the integral multiple of h/2pie 
so, angular momentum = mvr = nh/2pie 
4- acc to bohr if the electrons will revolve in these orbits then they will not loose energy acc to the concept of electromagnetic rediation . 
5- he gave these name of the orbit as quantised orbit . 
6- also he added that suppose a electron moving in a particular orbit , then if it gains some energy from outside then it will make a transition and go to the next higher orbit . 
and after sometime , it again loose those energy and will come to the lower energy state again  as low energy state are quite stable . 
7- BOHR model are also in accordance to de broglie hypothesis who said moving particle have both particle and wave nature . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
