Which of the following statements does not form a part of Bohr's model of hydrogen atom?

Which one of the following statements in relation to the hydrogen atom is correct?

What is the magnetic moment of Ti²⁺ ? (Given : Atomic number = 22)

If Rydberg constant is same for all elements, the angular momentum and energy of Li²⁺ of which orbital is equal to angular momentum and energy of 1 s-orbital of hydrogen atom?

Ionisation energy for H⁺ ion is proportional to rⁿ, then value of n is

Rutherford model could not explain

Ionisation energy of H-atom is 13.6 eV. The wavelengths of the spectral line emitted when an electron in Be³⁺ comes them 5th energy level to 2nd energy level is

If the quantum number I could have the value 'n' also then, Sc(21) would have electronic configuration as (other rules strictly followed)
