Quantum Theory and the Electronic Structure of Atoms

See attachment, please help me, by showing the work so I can use it as a study guide. The questions are regarding quantum theory and the electronic structure of atoms.

Uranium 238 can absorb a neutron and fission into two pieces. Identify the nucleus missing thethe reaction in the attached file.
Describe the resultant nucleus in each of the following reactions:
(see attachment for reactions)
What was Louis de Broglie's main contribution to quantumtheory?

1)For n=4, what are the possible values of l?
2)For l=2, what are the possible values of m1?
3)If m1 is 2, what are the possible values for l (for all atoms in their ground states that are known to exist)?

Consider the Earth-Sun system as a giant-sized hydrogen atom, the objects interacting, however, by the gravitational force. (a) What is thequantum number, according to Bohr Theory, for the Earth's orbit about the Sun? (b) If the Earth were to make a transition to the next lowest quantum state, by what amount would its distance

a) The electron in a hydrogen atom is in the l=1 state having the lowest possible energy andthe highest possible value for m1. What are the n, l, and m1 quantum numbers?
b) A particle is moving in an unknown central potential. The wave function of the particle is spherically symmetric. What are the values of l and m1?

Suppose you take a trip to a distant universe and find that the periodic table there is derived from an arrangement of quantum numbers different from the one on Earth. The rules in that universe are:
1. principal quantum number n = 1, 2, ... (as on Earth);
2. angular momentum quantum number l = 0, 1, 2, ... n - 1 (as on Ear

a) Draw the Lewis structure of nitramide with a single bond between the two nitrogen atomsand include formal charges. Are there any resonance structures? If so, please draw these too. Describe the hybridization of the nitrogen atoms.
b) Using the same atom connectivity as above, draw a Lewis structure with a double bond betwe

Consider theelectronicstructure of the element bismuth.
a) The first ionization energy of bismuth is Ei1 = +703 kJ / mol. What is the longest possible wavelength of light that could ionize an atom of bismuth?
b) Write theelectronic configurations of neutral Bi and Bi+ cation.
c) What are the n and l quantum numbers of the

A particle of mass m moves in two dimensions under the influence of the potential V(x,y)=1/2 m?^2 (((6x)^2)-2xy+(6y)^2 ). Using the rotated coordinates u=(x+y)/?2 and w=(x-y)/?2 show that the SchrÃ¶dinger equation in the new coordinates (u,w) is
-(?^2)/2m ((d^2/du^2) +(d^2/dw^2))?(u,w)+V ?(u,w)?(u,w)=E?(u,w)
Where V ?(u,w) sho

Identify thequantum state (i.e. list the requisite quantum numbers) of the lowest energy level in a 3-D quantum well that has a zero probability of finding the electron in the center of thestructure.
