That is how we showcase electrons in an element or compound
Mr. Bob I still quite don't understand the difference between Lewis diagram and Bohr diagram
First lets discuss valence eletrons, they are the electrons in the outer shell of an atom, responsible for the chemical properties of the atom.
It's a simple concept Billy, here I will show you.
While both diagrams showcase the amount of electrons in an element or compound, one of them shows only the valence electrons while the other diagram showcases all the electrons including the valence electrons in specific shells around the nucleus. A Bohr diagram gives us more details while the Lewis Diagram takes much less time but gives us the amount of valence electrons quicker
As you can see those dots represent electrons, Chlorine known as Cl has 17 electrons, all shown in the Bohr diagram but only 7 of these electrons are valence electrons shown in the Lewis Diagram
The diagram to the left is a Lewis dot diagram as it only shows the valence electrons while the one to the right is a Bohr Diagram as it shows all the electrons of Chlorine in their specific shells around the nucleus
