Argon Lewis Dot Structure: Drawing and Detailed Explanations

Argon Lewis dot structure plays a significant role in providing the idea about the concept of Lewis dot structure, as Argon is a noble gas and holds compete electronic configuration. This article would describe this fact broadly here.

We can discuss the matter through a systematic way by describing the features related to Argon Lewis dot structure. Those are:

Argon Lewis dot structure

The Lewis dot structure of Argon is the electronic. The electrons would be represented with the dot. Dots are the symbol of the electrons. Lewis dot structure is one of the key to open up several molecular facts regarding the formation of an element.

The position in periodic table of the element Argon is defined by the electronic configuration of the atom. Argon is called a noble gas as it exists in gaseous state and it holds a complete electron structure.

Molecular structure of Argon from Wikipedia

The atomic number of Argon is 18. It has eight electrons in its highest energy level. Therefore, this is obvious that the atomic structure of the element gets the highest stability in compare to all the other elements of periodic table.

Argon has no need to share or donate electrons, as it has no void space in its electronic configuration. The electronic configuration of this element is [Ar] 3s2 3p6. As the element has no urge of electron gaining or losing its does not need to crate bonds with other element of the table.

Argon is considered as the idea atom, which is an idol for other and in the periodic table the other elements in the series of Argon has a wish to get the same electronic structure like this atom. It can be said that the Lewis dot structure of Argon is quite simple, as the atom does not create positive or negative charges.


In the case of drawing the molecular structure of the element, the first step should be the identification of simple atomic structure of the element. The simple atomic structure of Argon has been represented below:

The calculation of the valance electrons present in the last electronic shell of Argon would provide the knowledge about how to draw Lewis dot structure of the atom. In the last electronic shell Argon, possess eight electrons, which is a filled octet.

Argon Lewis Dot structure from Wikipedia

Lewis structure is only responsible for highlighting the last shell of electron. The number of electrons here is shown by dots. Eight electrons of the last shell have been implemented through dots in this structure.

The molecular structure has been represented by the Lewis dot structure with mentioning the number of electrons. The fundamental need of understanding the facts about Argon and e reason behind being idea is supported by this drawing.

Facts represented by this structure 

Lewis dot structure is a shape of evaluating the internal design of the element. The facts are quite knowledgeable about Argon to show the frequency of other elements, which belong the same series of Argon in periodic table.

The Lewis dot structure of Argon shows the ability of the element to influence other atoms for engaging them in the electron sharing and transferring method. The ideal behaviour of the main fact about Argon, which is represented by this element.

This structure is reliable in giving the closure to know that the ideal structure of Argon and the other element on the same group is the driving force for other atoms in periodic table. The most stable element I the periodic table does not need to share of donate electrons to others.  

However, the overall structure is very simple and clarifies the existence of octet rule for other elements. The filled octet proofs that Argon is not capable of showing activities by participating ion chemical reaction.

Frequently Asked questions (FAQs)

Question 1: Why Argon is considered as the most Abundant noble gas in the Earth?

Answer: Argon is the 3rd most abundant gas in the Earth as it is found almost 70% in the planet “Mercury.” It is the most abundant noble gas due to the property of this inert gas to produce radioactive isotope of potassium which is basically long-lived element and highly harmful for lives in the Earth.

Question 2: Why Argon does not undergo chemical reactions?

Answer: The last shell of electron in the element is filled with eight electrons. This is the element, which influences other element in the same series to undergo electron-sharing method but does not need to share of transfer electrons itself. In this same reason, Argon is considered as an inert gas as well.

Question 3: Do all the noble gas on group 18 possess same atomic number and electronic configuration?

Answer: All the inert or noble gases in group 18 do not holds the same atomic number obviously but the basic electronic configuration of all the elements is similar and it shows compete distribution of electrons in the shells and no void in the last energy level.

Question 4: Does octet rule is applicable for Argon?

Answer: Octet is rule is not applicable fort Argon as it already has eight electrons in its last electron shells. There is no urge of having electrons for argon.

Question 5: Why Bromine, a halogen element tends to have the electronic configuration like Argon?

Answer: Broman is in the same period of elements in periodic table. The nearest Noble gas is Argon for bromine. Therefore, it has huge affinity towards making the same electronic configuration alike Argon and filled octet to have the ultimate stability in the periodic table.
