1. (a) Which "bold and daring" proposal did Bohr make to overcome the predictions of
classical mechanics of an electron spiralling into the nucleus?
(b) Explaining all the assumptions made and the terms used, show that the radius for the nth
orbit of Bohr's model of the hydrogen atom is given by:
h?
r. =
47 kme?
Show also, that the energy of the electron in the nth orbit is given by:
me

2. (i)What do you understand by Pauli's exclusion principle?
(ii) Write down all possible combinations of the quantum numbers for electrons filling
completely the p shell for n=2
What are the most significant differences between the Bohr model of the hydrogen atom and the Schrödinger analysis? What are the similarities?
If you look at it, there is an Ag atom with an atomic number of 47. Then, there are electrons from outside hitting electrons in the base shell (n=1) :
a. how much energy does the electron need to bounce off? and is there any energy absorbed by the electrons?
b. How much the radiation energy and wavelength produced by the transition of electrons from the L shell (n=2) to the ground shell (n=1) in filling the electron holes?
