With neon (Ne), the second energy level has been completed, 1s2 2s2 2p6. Atoms of period 3 elements begin filling the 3rd energy level (M shell).

That means that its subshells are completely filled with electrons and its last electrons fill p-subshell. So the element must be a p-block element from t 2009-07-01 41 Questions Show answers. Question 1. SURVEY.

Now, the energy of the eigenstate of the hydrogen atom characterized by the quantum numbers n, l, m is E = E0 / n2, where the ground-state energy E0 is specified in Equation ( [e9.56] ). Hence, the energy of the photon emitted during a 2P → 1S transition is ℏω = E0 / 4 − E0 = − 3 4 E0 = 10.2eV.
