Question

(i) Using Bohr's second postulate of quantization of orbital angular momentum, show that the circumference of the electron in the n^th orbital  state in hydrogrn atom is n times the de-Broglie wavelength associated with it.

(ii) The electron in hydrogen atom is initially in the third excited state .which can be emitted when it finally moves  to the ground state ?

Answer 1

(i) According to Bohr's second postulate

n₁ = 3 to n₁ = 2, 1

n₁ = 2 to n₁ = 1

 Total number of transition = 6
