Bohr model is applicable to: one electron atom. (true/false)

The simple Bohr model is not applicable to He^4 atom because.

Bohr's model can explain

The set of quantum numbers not applicable for an electron in an atom is

Rutherford model could not explain the stability of the atom and line spectrum of hydrogen atom. (true/false)

Using the Bohr model. Calculate the electric current created by the electron when the H-atom is in the ground state.

(a) Using the Bohr's model calculate speed of electron in hydrogen atom in the n = 1, 2, and 3 levels. (b) Calculate the orbital period in each of these levels.

For a hypothetical hydrogen like atom, the potential energy of the system is given by U(r)=(-Ke^(2))/(r^(3)) , where r is the distance between the two particles. If Bohr's model of quantization of angular momentum is applicable then velocity of particle is given by:

The energy required to knock an electron completely out of an atom is called excitation energy. (true/false)

In Bohr's model of hydrogen atom, the electron moves around the nucleus in a circular orbit of radius 5xx10^-11 m. Its time period is 1.5 xx 10^-16 s. The current associated with the electron motion is
