Dot Diagram O2. It holds the two hydrogen atoms together to form a hydrogen molecule. Valence electron is the number of electrons that lies in the outermost orbit of an atom.
Here are the dot and cross diagrams for. Valence electron is the number of electrons that lies in the outermost orbit of an atom. Lewis electron dot structure for o2 molecule an oxygen atom has 6 valence electrons in the valence shell and so it needs 2 more to complete the octet.
The lewis diagram of o2 shows two oxygen atoms having twelve dots of valence electrons.
There are three shared spaces between the circles so add a dot and cross to each one. Now this is only one way we can draw the electron dot diagram for oxygen. These four valence electrons form two shared pairs of covalent bonds providing a stable structure to the oxygen molecule. Ok were going to do the lewis dot structure for o2.
