NEET Physics Structure Of Atom Class 11 Questions

Taking the Bohr radius as a₀ = 53 pm, the radius of Li⁺⁺ ion in its ground state, on the basis of Bohr’s model, will be about

What is the ratio of the shortest wavelength of the Balmer series to the shortest wavelength of the Lyman series?

Choose the correct option from the following options given below: (1) In the ground state of Rutherford's model electrons are in stable equilibrium. While in Thomson's model electrons always experience a net-force. (2) An atom has a nearly continuous mass distribution in a Rutherford's model but has a highly non-uniform mass distribution in Thomson's model. (3) A classical atom based on Rutherford's model is doomed to collapse. (4) The positively charged part of the atom possesses most of the mass in Rutherford's model but not in Thomson's model.

Hydrogen atom from excited state comes to the ground by emitting a photon of wavelength \( \lambda \). The value of principal quantum number 'n' of the excited state will be : (R : Rydberg constant)

The angular momentum of an electron moving in an orbit of hydrogen atom is 1.5 ℏ/π. The energy in the same orbit is nearly.

If radius of second Bohr orbit of the He⁺ ion is 105.8 pm, what is the radius of third Bohr orbit of Li²⁺ ion?
