Question

For an electron in the second orbit of hydrogen, what is the moment of momentum as per the Bohr's model?

पर्याय

• πh

• 2h/π

• h/π

• 2πh

Answer 1

h/π

Explanation:

The angular momentum of the electron in permitted orbits is given by L= nh/2 in Bohr's model of the hydrogen atom, where n = 1, 2, 3,...

For the second orbit n = 2. L = 2 h/2π = h/π
