Calculate the ground state energy of a helium atom in a box of 1cm on a side. Solution: these are constants that we will see again and again. I set c = 1. In the ground state = 3, the helium mass is about 4 times the proton mass, and using , the energy is roughly E = [4(10^6)10(3)]/[2(4)(10^9)(10^16)] ~ 1.5 x 10^(-18) ev. This is a small energy, especially when compared to room temperature energy of .025 ev. You...
