Question

What is the angular momentum of an electron in Bohr’s hydrogen atom whose energy is –3.4 eV?​

Answer 1

Answer:

h/π

Explanation:

Energy -3.4 is the energy in the second energy level .

13.6 /n^2 = 3.4

therefore n=2 .

so angular momentum in Bohrs Model is quantised.

mvr = Angular momentum= nh/2π

So L = 2h/2π = h/π
