What is electron dot notation?
A method of describing how many electrons are in the highest energy level in an electron. It is done by writing an element’s symbol (i.e. for Hydrogen, H; and for Neon, Ne) and then placing dots around the symbol in a counter-clockwise manner. The maximum dots there can ever be is 8 (there are theorems that prove it, I believe the Aufbau Principle is the one). Their are several teachings in which the order the dots should be drawn. However, there is a consensus that up to two dots may be placed on any side of the symbol (2 on the right, 2 on top, 2 on the left, and 2 on bottom).
