In hydrogen atom electron jumps from the third orbit to the first orbit. Change in angular momentum is ?
Answers
answer : change in angular momentum is h/π
This is based on Bohr's model of atomic structure.
according to his theory, “ angular momentum of an electron in an orbital is integral multiple of h/2π.
i.e., angular momentum of nth orbit = nh/2π.
so, angular momentum of 3rd orbit = 3h/2π
similarly, angular momentum of 1st orbit = h/2π
then change in angular momentum = 3h/2π - h/2π = h/π.
hence, change in angular momentum would be h/π.
[note : if answer is numerical value. just put h = 6.63 × 10^-34 and π = 3.14 and you will get change in momentum = 2.11 × 10^-34 J/s ]
