Solved MCQ based on Bohr’s atomic model
1Q. According to Bohr's theory the energy required for the transition of H atom from n = 6 to n = 8 state is :
2Q. The energy of the electron in an orbit of hydrogen atom is given by
𝐸_𝑛=−1311.8/𝑛^2 𝑘𝐽 〖𝑚𝑜𝑙〗^(−1)The ionisation energy of hydrogen atom is
3Q. The ratio of the radius of Bohr first orbit for the electron orbiting the hydrogen nucleus to that of the electron orbiting the deuterium nucleus (mass nearly twice that of H nucleus) is approximately is
4Q. The ratio of radii of the first three Bohr orbits of H-atom is:
5Q. The energy of an electron in the second Bohr orbit of H-atom is -E. The energy of the electron in the Bohr's first orbit is:
6Q. The energy of the second Bohr orbit of H atom is -3.41 eV. The energy of the second Bohr orbit of He+ ion is
7Q. The frequency of radiations emitted when electron falls from n = 4 to n = 1 in H-atom would be
8Q. The energy of second Bohr's orbit in H-atom is —328 k J mol-1 , hence the energy of fourth Bohr's orbit would be
