The Lewis Electron-Dot Symbols of Elements. Gilbert N Lewis is widely known for his use of simple symbolic representations of elements that show valence electrons as dots. You've seen the Bohr's diagram for the first 18 elements. Sometimes it is more convenient to represent the elements by its Lewis electron dot symbol.
So their electron clouds reconfigure into lower energy, more stable shapes. For common chemicals, most of the time, this produces an octet. Remember that octets aren’t a law of nature; they’re “magic numberw. To learn more about octets, Lewis theory, and magic numbers, see: Lewis theory, Dot Diagrams and Magic Numbers
The equation also shows us that as the electron’s energy increases (as n increases), the electron is found at greater distances from the nucleus. This is implied by the inverse dependence on r in the Coulomb potential, since, as the electron moves away from the nucleus, the electrostatic attraction between it and the nucleus decreases, and it is held less tightly in the atom.
