Such was the case when iupac recently reviewed elements 113, 115, 117 and 118, and decided to give them official names and symbols (goodbye, ununseptium and hello, tennessine!).

Electron energy levels periodic table. N shell, n = 4. The highest energy form of electromagnetic waves are gamma (γ) rays and the lowest energy form are radio waves. When the third energy level has 8 electrons, the next 2 electrons go into the fourth energy level.
