Choose the correct statements from the following:

A. The minimum energy required to free the electron from the ground state of the hydrogen atom is 13.6 J
B. The principle quantum number n labels the stationary states in the ascending order of energy
C. Bohr gave the basic idea of discrete energy levels
D. de Broglie hypothesis provided an explanation for Bohr's second postulate for the quantization of angular momentum of the orbiting electron
E. line spectrum provides useful information about the atomic structure.

Choose the correct answer from the options given below:

B, C, D and E only

The correct answer is Option (3) → B, C, D and E only

A. The minimum energy required to free the electron from the ground state of the hydrogen atom is 13.6 J: This is incorrect. The correct value is 13.6 eV, not 13.6 J.

(B) In the Bohr Model, the energy levels are labeled by principle quantum number n, where energy increases with n.

(C) Bohr atomic model introduced the concept of discrete energy levels for electrons in the atom.

(D) The De-Broglie hypothesis states that the electrons have wave - like properties, and the quantization of angular momentum corresponds to the condition that an integral number of wavelength must fit along the orbital circumference.

(E) The discrete lines in the atomic spectrum arise form electronic transitions between energy levels and provide valuable insights from the structure of atom.
