1. we want to find the Energy of Assembly for the helium (EoA) atom. This atom has two protons in the nucleus, and two outer electrons each at a radius of about 0.5nm (nanometers) from the nucleus. Follow these steps to calculate the EoA. The value of "e" is e = 1.6 x 10^-19 C.
A. Show with the nucleus, and bring in one of the elctrons
(Show this on the drawing) >>>> Initial Configuration
Below, Calculate the energy involved:
Energy (pp+e) _________
B. Now bring in a second electron. Show all interactios
(assume this is an equilateral triangle)
Below, calculate all the energy terms involved
(Show this on the drawing) >>>>
^ Final Configuration ^
(pp + e ) + e Energy (all aditional terms) __________
C. What is the total Energy of Assembly?

2. In the derivation of the energy levels in the hydrogen atom one commonly assumes that the nucleus is a point charge. However, in reality the size of the nucleus is of the order of Im = 10-15m. Since this is very much smaller than the typical distance of the electron from the nucleus, which is of the order of a0-0.5A = 0.5 × 10-10m, the finite size of the nucleus can be taken into account perturbatively. (a) Assume that...
