Question

Is the rule that the outermost orbit cannot have more than 8 electrons true dor all the elements?

Answer 1

Answer:

In atomic physics, the Landé interval rule states that, due to weak angular momentum coupling (either spin-orbit or spin-spin coupling), the energy splitting between successive sub-levels are proportional to the total angular momentum quantum number (J or F) of the sub-level with the larger of their total angular
