Let's do a quick estimate of the ground-state energy of a slightly fictitious Boron atom - fake in that I will make up the effective nuclear charges. Its electrons each have a hydrogenic energy given by the formula hcRn2Zeff2 with the effective nuclear charges given below: Zeff(1s)=4.4Zeff(2s)=3.4Zeff(2p)=2.4 Compute the total energy of the atom as a multiple of hcR by adding the energies for each of the five electrons. Don't forget the negative sign in the energy
