It is a classic example of chemistry being full of exceptions!Ĭhlorine belongs to the third group in the periodic table. Here, an anomaly exists with the chlorine atom as it can increase its octet to accommodate more valence electrons. Step 2: Find the valence electrons further needed to stabilize the molecule.īy the octet rule, each element needs eight valence electrons to complete its electronic configuration. So, the total number of valence electrons available in one chlorine dioxide or chlorite molecule is 20. There are two oxygen molecules in chlorine dioxide so the total is 19.īut chlorine dioxide exists as ClO2- during the formation of a bond, therefore we have one more valence electron available. It is 20 as chlorine has 7 valence electrons and oxygen has 6 valence electrons. Step 1: Find the total valence electrons in one molecule of chlorine dioxide.
Let us follow some steps to draw the Lewis structure of chlorine dioxide: We will draw the Lewis structure of chlorine dioxide with 20 valence electrons. Due to this, the valence electrons in chlorine dioxide or chlorite are 20. This arises from the fact that chlorine dioxide is an unstable molecule and mainly exists as ClO2- during bond formation. Here, it is crucial to understand that chlorine dioxide is a strong anion and oxidizing agent. It might confuse many people as ClO2 comprises 19 valence electrons only. Now, it will be easier to draw the Lewis structure of chlorine dioxide as we know that there are 20 valence electrons in one chlorine dioxide molecule.
To begin drawing the Lewis structure of Chlorine dioxide, first, it is essential to draw one for the participating elements.Įlectronic Configuration = 1s2 2s2 2p6 3s2 3p5 The Lewis structure is a pictorial representation of valence electrons taking part in the formation of bonds to produce a new molecule with new properties altogether.

O3 is a molecule of oxygen, that is a particle composed to two or more atoms which can either be different, as is the case for a compound, or the same as it is for an element. Because, around the central oxygen, there are 5 electrons (2 from the double bond, 1 from the single bond, and 2 from the lone pair), we assign this centre a positive charge,… A reasonable Lewis structure would be: O = O+ −O−. The O3 bond angle will be 116 degrees since it has a Bent molecular geometry.Įxplanation: The ozone molecule is O3, and each O centre contributes 6 electrons to the valence shell. As a result they will be pushed down giving the O3 molecule a bent molecular geometry or shape. What is the electron pair geometry for O3?īased on VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) these electrons will repel the electron clouds of the two Oxygen atoms on the end. Ozone layer had O3 molecules and this form of oxygen is also called ozone.Īll four electron pairs are not the same,out of four two are bond pairs and two are lone pairs. The function is this layer is to protect the surface of Earth from harmful UV rays. It’s a layer lying up there in Stratosphere (the 2nd layer of atmosphere). Lewis structure of O3 can be drawn by starting from valence electrons of oxygen atoms in several steps. Also, there are charges in two oxygen atoms in O3 lewis structure. In the lewis structure of ozone, there are one double bond and one single bond. Ozone (O3) is an allotrope of oxygen and contains three oxygen atoms.
