Cesium as its electron configuration is [Xe] 6s1 .
others like for O it is [He] 2s2 2p4 and for Se it is [Ar] 3d10 4s2 4p4 .
So only Cs has six energy levels as its principal quantum no is 6.

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...
